Re: CHKOBJ for IFS object

["System Support Products, Inc." <sspi@xxxxxxxxxxxxx>]

Rob,

   I've been using the CHKIN command to do a quick and dirty IFS file
existence test.  Although the documentation for the CHKIN command says that
the command is not supported for all file systems, I have found that it will
tell you that the object doesn't exist before it complains about the file
system.  If you get the message 'File system is unsupported', then the
object is there.

   Another more reliable way to check for IFS files is to use CL to call the
'stat' C function.  Bruce Vining was kind enough to post this code back when
I asked this same question, you might want to try this:

-------------------------------------------------------------------
             PGM        PARM(&PARM)
             DCL        VAR(&PARM) TYPE(*CHAR) LEN(32)
             DCL        VAR(&RTNVALINT) TYPE(*CHAR) LEN(4)
             DCL        VAR(&RTNVAL) TYPE(*CHAR) LEN(2)
             DCL        VAR(&PATH) TYPE(*CHAR) LEN(100)
             DCL        VAR(&NULL) TYPE(*CHAR) LEN(1) VALUE(X'00')
             DCL        VAR(&BUF) TYPE(*CHAR) LEN(4096)
             CHGVAR     VAR(&PATH) VALUE(&PARM *TCAT &NULL)
             CALLPRC    PRC('stat') PARM(&PATH &BUF) +
                          RTNVAL(%BIN(&RTNVALINT 1 4))
             CHGVAR     VAR(&RTNVAL) VALUE(%BIN(&RTNVALINT))
             IF         COND(&RTNVAL = '00') THEN(SNDMSG MSG('Found') +
                          TOUSR(VINING))
             ELSE       CMD(SNDMSG MSG('Not found') TOUSR(VINING))
             ENDPGM

IFS?  For example if I perform the following:

TOSTMF('/TEMP/DUH.TXT')

this API it deletes the message, on it's own time.  Well, I loop from one
user to the next and I need to wait until IBM is done sending the stream
file before recreating it so I can send to the next person.
