NAME
PX_read_blobdata — Read blob from file (deprecated)
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.
