bdfp1m1b | Programming Concepts and Reference |
Use this group of functions to check if a SW00SR slot exists. If the slot exists, the function that was called returns the base address of the SW00SR slot.
You can use these functions to test if a particular subfile is open.
Format
dft_fil *dfifb_fst();
dft_fil *dfifb_nxt();
dft_fil *dfifb_ref(dft_ref *ref);
dft_fil *dfifb_ref_new(dft_ref *ref, dft_ref *new);
Entry Requirements
None.
Normal Return
The address of the SW00SR slot.
Error Return
NULL pointer.
Programming Considerations
Examples
if(dfifb_ref("GR95SR ") != NULL) /* then subfile GR95SR is open */
file_ptr = dfifb_fst();
