I assume you meant '\0' and not '0'. Unless Jobn has been assigned a string previously, strcmp should fail. (Actually it would invoke undefined behavior.)
strcpy does not care about the previous contents of the destination. (strcat does but that is a different function.) If the length of xxxxx plus the terminating nul fits in Jobn, strcpy will replace as much of the original contents as needed and will insure that it is properly terminated. The remaining portion of Jobn will be unchanged. Your memset serves no apparent purpose. :>: -----Original Message----- :>: From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On :>: Behalf Of Scott Ford :>: Sent: Tuesday, September 04, 2012 12:04 PM :>: To: IBM-MAIN@LISTSERV.UA.EDU :>: Subject: Re: Strings (hijacked from: The IBM zEnterprise EC12 :>: announcment) :>: :>: I have had to move a string type field like a parameter to a field like :>: this, :>: :>: Jobn char[40]; :>: :>: memset(Jobn,'0',sizeof(Jobn)); :>: strcpy(Jobn,xxxxx); :>: :>: Otherwise strcmp fails, where xxxxx is the parameter string :>: :>: Scott ford :>: www.identityforge.com :>: :>: On Sep 4, 2012, at 1:05 PM, retired mainframer <retired- :>: mainfra...@q.com> wrote: :>: :>: > The construct :>: > char x[3] = "ABC"; :>: > will legally initialize an array of char without adding the '\0'.
