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.
