Buck,
I have done this and it works very well. Here is a snipet of the code.
*Data structure that needs to go along with Read Directory operation
D DirEnt DS BASED(Entry)
D D_Reserved 16A
D D_fileeno 10U 0
D D_fileno 10U 0
D D_reclen 10U 0
D D_res2 10I 0
D D_res3 6A
D D_res4 2A
D ccsid 10I 0
D country_id 2A
D language_ID 3A
D nls_res5 3A
D D_namelen 10U 0
D D_name 640A
D DirNamZ S 50A INZ(' ' )
D DirNamP S * INZ(%ADDR(DirNamz))
C EVAL DirNamz = %TRIM(DirNam) + ZeroBin
C Eval Dir = opendir(DirNamp)
C IF Dir = NUL
C EVAL RC = perror(Dir)
C Eval errmsg = 'Error in opening Dir+
C ectory'
C Eval errorpage = errpag(errmsg)
C Eval errdly = 1
C Return
C EndIf
C Eval Entry = readdir(Dir)
Once you know the file name you canuse Unlink to delete it
C Eval RL = unlink(FileNamP)
My Header file looks like this:
* Open Directory Operation
* value returned = file descriptor 0 (OK), -1 (Error)
Dopendir PR * EXTPROC('opendir')
D * VALUE
* Read Directory Operation
*
Dreaddir PR * EXTPROC('readdir')
D * VALUE
* Open Directory Operation
* value returned = 0 (OK) or , -1 (Error)
Dclosedir PR 10I 0 EXTPROC('closedir')
D * VALUE
* Unlink a File from system... Delete File
* value returned = 0 (OK) or , -1 (Error)
Dunlink PR 10I 0 EXTPROC('unlink')
D * VALUE
