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.
