Function Documentation

LBMSDMExpDLL int lbmsdm_msg_get_blob_idx ( lbmsdm_msg_t Message,
size_t  Index,
void *  Value,
size_t *  Size 
)

Fetch a BLOB field value from a message by field index.

Parameters
MessageThe SDM message from which the field is to be fetched.
IndexField index.
ValuePointer to variable where the value is stored.
SizePointer to a variable containing the maximum size of Value in bytes. On exit, it will contain the actual size of Value.
Return values
LBMSDM_SUCCESSif successful
LBMSDM_INSUFFICIENT_BUFFER_LENGTHif Size is not large enough for the data. Size will contain the length required.
LBMSDM_FAILUREotherwise.
