BPX1FST (fstat) example

The following code gets the file status for the file opened as FILEDESC. For the callable service, see fstat (BPX1FST, BPX4FST) — Get status information about a file by descriptor. For the data structure, see BPXYSTAT — Map the response structure for stat. AMODE 64 callers use BPX4FST (fstat) example.
