SYNOPSIS
#include <paradox.h>
int PX_set_blob_file(pxdoc_t *pxdoc, const char *filename)
DESCRIPTION
Opens or creates the given blob file and associates it with the Paradox
database. This function must be called before accessing records
whose blob data is stored in a .MB file. It must also be called after
opening or creating the paradox database. If the blob data is contained
in the record itself or can be stored in the record, this function may
not be called.
This function must be called after opening or creating the database
file, because it uses the same file open mode. If you call it before
PX_open_file(3) or PX_create_file(3) it will quit with an error.
RETURN VALUE
Returns a value < 0 in case of an error, otherwise 0.
