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.
