GN_Wfn, Fetch next match for wildcard string
Register parameters
RST 20H, DEFW $5609
IN: DE = 0,1,2; not allowed DE = pointer to buffer for explicit name (should be > 255) C = buffer size (limit of space to use) IX = wildcard handle (previosly allocated with GN_Opw) OUT, if call successful: Fc = 0 DE = pointer to null-terminator of explicit name B = number of segments in filename C = number of characters in explicit filename A = DOR type (DN_FIL = file, DN_DIR = directory or DM_DEV = device) If the wildcard contained :ROM.*//* then DN_APL would be returned. OUT, if call failed: Fc = 1 A = error code: RC_BAD ($04), bad arguments RC_EOF ($09), no more matches RC_HAND ($08), bad handle Registers changed after return: ...C..HL/IXIY same AFB.DE../.... different
Notes
The DOR type is useful to find a particular type of information, eg. directories.
