char* PX_read_blobdata(pxblob_t *pxblob, const char *data, int len, int *mod_nr, int *blobsize) 
.SH "DESCRIPTION" 
.PP 
Reads blob data from the given blob document (.MB file) 
passed as the 
first parameter. \fBdata\fP is the data stored in the 
blob field of the db file. \fBlen\fP 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. 
 
.PP 
This function is deprecated. Use 
\fBPX_set_blob_file(3)\fP 			and \fBPX_get_data_blob(3)\fP 			or \fBPX_get_data_graphic(3)\fP instead. 
 
.SH "RETURNS" 
.PP 
Returns NULL in case of an error or a pointer to the blob 
data. \fBmod_nr\fP contains the modification number of 
the blob and \fBblobsize\fP contains the length of 
the blob data. The modification number can be used as a unique 
id for the blob.
