SYNOPSIS
#include <paradox.h>
char* PX_read_blobdata(pxblob_t *pxblob, const char *data, int len, int *mod_nr, int *blobsize)
DESCRIPTION
Reads blob data from the given blob document (.MB file)
passed as the
first parameter. data is the data stored in the
blob field of the db file. len is the length
of that field. The function hides everything needed for evaluating
the field data. It can handle both single blob blocks and
suballocated blocks.
This function is deprecated. Use
PX_set_blob_file(3) and PX_get_data_blob(3) or PX_get_data_graphic(3) instead.
RETURNS
Returns NULL in case of an error or a pointer to the blob data. mod_nr contains the modification number of the blob and blobsize contains the length of the blob data. The modification number can be used as a unique id for the blob.
