cpiBufferSize
This function gets the size of the buffer that contains the bit stream representation of the input message, for the specified parser object.
Syntax
CciSize cpiBufferSize(
int* returnCode,
CciParser* parser);
Parameters
- returnCode
- Receives the return code from the function (output). Possible return codes are:
- CCI_SUCCESS
- CCI_EXCEPTION
- CCI_INV_PARSER_OBJECT
- CCI_NO_BUFFER_EXISTS
- parser
- Specifies the address of the parser object (input).
Return values
If successful, the size of the buffer, in bytes, is returned. If an error occurs, zero (CCI_NULL_ADDR) is returned, and returnCode indicates the reason for the error.
Sample
This example is taken from the sample node file BipSampPluginParser.c:
int cpiParseBufferEncoded(
CciParser* parser,
CciContext* context,
int encoding,
int ccsid
){
PARSER_CONTEXT_ST* pc = (PARSER_CONTEXT_ST *)context ;
int rc;
/* Get a pointer to the message buffer and set the offset */
pc->iBuffer = (void *)cpiBufferPointer(&rc, parser);
pc->iIndex = 0;
/* Save the format of the buffer */
pc->iEncoding = encoding;
pc->iCcsid = ccsid;
/* Save size of the buffer */
pc->iSize = cpiBufferSize(&rc, parser);
