This function is an extension of the capability provided by the existing cpiParseBuffer() implementation function that provides the encoding and coded character set that the input message is represented in. If this implementation function is provided in the CPI_VFT structure, neither cpiParseBuffer() nor cpiParseBufferFormatted() can be specified, otherwise the cpiDefineParserClass() function will fail with a return code of CCI_INVALID_IMPL_FUNCTION.

int cpiParseBufferEncoded( CciParser* parser, CciContext* context, int encoding, int ccsid);
The size (in bytes) of the remaining portion of the message buffer for which the parser takes ownership.
This example is taken from the sample parser file BipSampPluginParser.c (lines 428 to 466):
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); /* Prime the first byte in the stream */ pc->iCurrentCharacter = cpiBufferByte(&rc, parser, pc->iIndex); /* Set the current element to the root element */ pc->iCurrentElement = cpiRootElement(&rc, parser); /* Reset flag to ensure parsing is reset correctly */ pc->iInTag = 0; if (pc->trace) { fprintf(pc->tracefile, "PLUGIN: <- cpiParseBufferEncoded() retvalue=%d\n", pc->iSize); fflush(pc->tracefile); }
