strdup is not part of the C standard library as defined by ANSI/ISO. I'm not certain but I believe it is part of the POSIX standard. The IBM manual claims it is also part of the X/Open Portability Guide 4.2.
If your cross platform concerns include MAC, Windows, Linux/Unix/Solaris/HPUX, embedded systems, etc., then your decision is driven in one direction by the C standard. If your concerns are more limited, such as just MVS, OS/390, and z/OS, then the IBM library might let you make a different decision. strdup is in the OS/390 2.10 version of the compiler and run-time library and I expect it has been carried forward to z/OS. You should check the Run-Time Library Reference since it seems like you need to define a special macro to" activate" it as an extension. -----Original Message----- From: Steve Rawlins [mailto:[EMAIL PROTECTED] Sent: Thursday, September 28, 2006 4:06 PM To: [email protected] Subject: C function strdup Anybody use function "strdup" (malloc & duplicate a string) from an MVS "C" program? We are using C compiler V2 R10 OS/390 C on ZOS v1.4 and we are trying to keep our code cross-platform compatible. Is strdup (string duplicate) function supported by MVS? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
