Re: Neater way of preparing call to system()

Hi Erik,

there are 2 possibilities I used for that purpose:
1. STRCPY.
Looks like this (extract from my program):
strcpy(szStr, "CRTDUPOBJ OBJ( ) FROMLIB( ) TOLIB(QTEMP) OBJTYPE(*FILE)") ;
memcpy(&szStr[34], KLIB, 7);
memcpy(&szStr[14], RepFileName, 10) ;
r1 = system(szStr) ;
I just leave empty spaces in the places, that receive values, because this CRTDUPOBJ is used more that once...
2. SPRINTF
sprintf(szStr, "CRTDUPOBJ OBJ(%s) FROMLIB(%s) TOLIB(QTEMP) OBJTYPE(*FILE)", KLIB, RepFileName);
r1 = system(szStr) ;
Here you must be sure, that strings KLIB and RepFileName (in my example) must be zero-terminated, otherwise you are in trouble.
If these strings are not zero-terminated, you must zero terminate them.
Do you need a code example that does that (trims spaces from the right and adds 0x00)?

Subject: [C400-L] Neater way of preparing call to system()


I need to issue a CPYF using system() that would look
something like this
from RPG:

cmdstring = 'CPYF FROMFILE(MYLIB/MYFILE) TOFILE+
(FTPLIB/FILEX) FROMMBR(' + %trimr(pmbr) +') +
TOMBR(' + %trimr(pmbr) + ') MBROPT(*REPLACE)
FMTOPT(*NOCHK)';

That is, the command is hard coded except for the member
names, which can be
anywhere between 2 and 10 bytes.
Does anyone have any good suggestions for a C/C++ equivalent?
The best I can
come up with at present includes a lot of inserts and appends
and would take
several lines.

Thanks,
Erik
