Detailed Description

Context initialization functions handle the allocation, initialization, and destruction of context variables (variables of type OSCTXT). These variables hold all of the working data used during the process of encoding or decoding a message. The context provides thread safe operation by isolating what would otherwise be global variables within this structure. The context variable is passed from function to function as a message is encoded or decoded and maintains state information on the encoding or decoding process.

#define OSRT_GET_FIRST_ERROR_INFO ( pctxt )

Value:

(((pctxt)->errInfo.list.head == 0) ? (OSRTErrInfo*)0 : \

(OSRTErrInfo*)((pctxt)->errInfo.list.head->data))

OSRTErrInfo

Definition: rtxContext.h:67

◆ rtxByteAlign

#define rtxByteAlign ( pctxt )

Value:

if ((pctxt)->buffer.bitOffset != 8) { \

(pctxt)->buffer.byteIndex++; (pctxt)->buffer.bitOffset = 8; }

This macro will byte-align the context buffer.

◆ rtxCtxtGetMsgLen

#define rtxCtxtGetMsgLen ( pctxt ) (pctxt)->buffer.byteIndex

This macro returns the length of an encoded message. It will only work for in-memory encoding, not for encode to stream.

Note that this macro will not work with ASN.1 BER in-memory encoding. In this case, the BER-specific version of the function must be used.

Parameters

pctxt Pointer to a context structure.

◆ rtxCtxtGetMsgPtr

#define rtxCtxtGetMsgPtr ( pctxt ) (pctxt)->buffer.data

This macro returns the start address of an encoded message. If a static buffer was used, this is simply the start address of the buffer. If dynamic encoding was done, this will return the start address of the dynamic buffer allocated by the encoder.

Note that this macro will not work with ASN.1 BER in-memory encoding. In this case, the BER-specific version of the function must be used.

Parameters

pctxt Pointer to a context structure.

◆ rtxCtxtPeekElemName

#define rtxCtxtPeekElemName ( pctxt )

Value:

(((pctxt)->elemNameStack.count > 0) ? \

(const OSUTF8CHAR*)(pctxt)->elemNameStack.tail->data : (const OSUTF8CHAR*)0)

This macro returns the last element name from the context stack.

Parameters

pctxt Pointer to a context structure.

Returns: Element name from top of stack or NULL if stack is empty.

◆ rtxCtxtSetProtocolVersion

#define rtxCtxtSetProtocolVersion	(	pctxt,
		value
	)	(pctxt)->version = value

This macro sets the protocol version in the context. This version number may be used in application code to do version specific operations. It is used in generated ASN.1 code with the extension addition version numbers to determine if an addition should be decoded.

For example, if this value is set to 8 and an extension addition group exists with version number 9 ([[ 9: ... ]]), its contents will not be decoded.

Parameters

pctxt	Pointer to a context structure.
value	The version number value.

◆ rtxCtxtTestFlag

#define rtxCtxtTestFlag	(	pctxt,
		mask
	)	(((pctxt)->flags & mask) != 0)

This macro tests if the given bit flag is set in the context.

Parameters

pctxt	- A pointer to a context structure.
mask	- Bit flag to be tested

This function creates a copy of a context structure. The copy is a "shallow copy" (i.e. new copies of dynamic memory blocks held within the context are not made, only the pointers are transferred to the new context structure). This function is mainly for use from within compiler-generated code.

Parameters

See also rtxCtxtPushContainer(Bits|Bytes)/rtxCtxtPopContainer

Parameters

pctxt Pointer to context structure.

Parameters

pctxt	Pointer to a context structure. This provides a storage area for the function to store all working variables that must be maintained between function calls.
bufaddr	A pointer to a memory buffer to use to encode a message or that holds a message to be decoded. The buffer should be declared as an array of unsigned characters (OCTETs).

◆ rtxFreeContext()

void rtxFreeContext ( OSCTXT * pctxt )

Parameters

pctxt Pointer to a context structure.

◆ rtxInitContext()

int rtxInitContext ( OSCTXT * pctxt )

This function initializes an OSCTXT block. It sets all key working parameters to their correct initial state values. It is required that this function be invoked before using a context variable.

NOTE: This as part of the common runtime, this is not intended to be called directly by user code; it does not initialize application-specific data structures (e.g. those used for ASN.1). If you are a user reading this, you may instead be interested in rtInitContext.

Parameters

pctxt Pointer to the context structure variable to be initialized.

Returns

Completion status of operation:

0 = success,
negative return value is error.

◆ rtxInitContextBuffer()

int rtxInitContextBuffer	(	OSCTXT *	pctxt,

This function assigns a message buffer to a context block. The block should have been previously initialized by rtxInitContext.

Parameters

pctxt	The pointer to the context structure variable to be initialized.
bufaddr	For encoding, the address of a memory buffer to receive the encoded message. If this address is NULL (0), encoding to a dynamic buffer will be done. For decoding, the address of a buffer that contains the message data to be decoded.
bufsiz	The size of the memory buffer. For encoding, this argument may be set to zero to indicate a dynamic memory buffer should be used.

Returns

Completion status of operation:

0 = success,
negative return value is error.

Parameters

pctxt	Pointer to the context structure variable to be initialized.
malloc_func	Pointer to the memory allocation function.
realloc_func	Pointer to the memory reallocation function.
free_func	Pointer to the memory deallocation function.

negative return value is error.

◆ rtxInitContextUsingKey()

int rtxInitContextUsingKey	(	OSCTXT *	pctxt,
		const OSOCTET *	key,
		OSSIZE	keylen
	)

This function initializes a context using a run-time key. This form is required for evaluation and limited distribution software. The compiler will generate a macro for rtXmlInitContext in the rtkey.h file that will invoke this function with the generated run-time key.

Parameters

pctxt	The pointer to the context structure variable to be initialized.
key	Key data generated by ASN1C compiler.
keylen	Key data field length.

Returns

Completion status of operation:

0 (ASN_OK) = success,
negative return value is error.

◆ rtxInitThreadContext()

int rtxInitThreadContext	(	OSCTXT *	pctxt,
		const OSCTXT *	pSrcCtxt
	)

This function initializes a context for use in a thread. It is the same as rtxInitContext except that it copies the pointer to constant data from the given source context into the newly initialized thread context. It is assumed that the source context has been initialized and the custom generated global initialization function has been called. The main purpose of this function is to prevent multiple copies of global static data from being created within different threads.

Parameters

pctxt	Pointer to the context structure variable to be initialized.
pSrcCtxt	Pointer to source context which has been fully initialized including a pointer to global constant data initialized via a call to a generated 'Init_<project>_Global' function.

Returns

Completion status of operation:

0 = success,
negative return value is error.

◆ rtxLicenseClose()

void rtxLicenseClose ( void )

Finish with current license and free internal resources. To avoid crashing your application:

Do not call this during an exit handler function registered with atexit().
Do not call this when another thread might concurrently trigger a license check by invoking methods in the asn1c runtime.

◆ rtxMarkPos()

int rtxMarkPos	(	OSCTXT *	pctxt,
		OSSIZE *	ppos
	)

This function saves the current position in a message buffer or stream. Note that this saves the byte offset only and does not consider the bit position. Therefore, it may not be suitable for use with the packed encoding rules (see rtxMarkBitPos).

Parameters

pctxt	Pointer to a context block.
ppos	Pointer to saved position.

Returns

Completion status of operation:

0 = success,
negative return value is error.
