realpath() syntax?

2012-04-11 Thread Paul Gilmartin 
z/OS 1.12.  The source:

/* Doc: Print the resolved pathname of each argument
*/
#include stdlib.h
/* appears to contain:
char*realpath(const char * __restrict__,
char * __restrict__);
*/

int main( int argc, char ** argv ) {

char *resolved_name;

/* This is OK.  */
realpath( xyzzy, NULL );

/* This is OK.  */
resolved_name = wombat;

/* this gets:
   ERROR CCN3068 realpath3.c:22
   Operation between types char* and int is not allowed. */
resolved_name = realpath( xyzzy, NULL );

}

My compile command is:

user@MVS:167$ gmake realpath3   
LC_CTYPE= c89 -I.. -D_XOPEN_SOURCE -D_OE_SOCKETS -Wa,ASA,RENT 
-DPLATFORM=OS390  -o realpath3 ../source/realpath3.c  /usr/lib/Xaw.x

FSUM3065 The COMPILE step ended with return code 12.

again.

Help!

Right.  And I would have expected that you should have gotten a compiler
warning about the assumed type of realpath being int, since a
declaration wasn't found without #define _XOPEN_SOURCE_EXTENDED 1

Also, according to the documentation you will get an EINVAL error if the
second argument (the buffer) is NULL.

I thought I saw that this had changed, perhaps at 1.13, to
implement a POSIX future direction.  Alas, no; I must have
been reading the OS X man page and displaced by wishful
thinking.

Works.  Thanks.  I failed to note in POSIX the dependency on
an option.  OS X, Linux, and Solaris all compile it with no such
special action.
