BPX1GMN (w_getmntent) example

The following code gets the mount entries for the caller. For the callable service, see w_getmntent (BPX1GMN, BPX4GMN) — Get information on mounted file systems. For the data structure, see BPXYMNTE — Map response and element structure of w_getmntent. AMODE 64 callers use BPX4GMN (w_getmntent) example.

If BPXYMNTE is assembled with MNTE2=YES, fields MNTEHID and MNTEHBLEN must be initialized.
