As far as I can tell, stdio.h will generate declaration for snprintf if

If it is defined, you are supposed to include ifs.h which will generate 
it.


I'm specifying OUTPUT(*PRINT) on my CRTCMOD:

Language level  . . . . . . . . :   *EXTENDED
Presumably, that causes __EXTENDED__ to be defined.

System interface options  . . . :   *NOIFSIO  *NOASYNCSIGNAL
Presumably, the *NOIFSIO causes __IFS_IO__ to be undefined.

In /qibm/include/stdio.h, it looks like the prototype for snprintf
will be defined #ifndef __IFS_IO__ and #if defined (__EXTENDED__) &&
(__OS400_TGTVRM__>=520), but I still get CZM0304  No function prototype
given for 'snprintf'. Of course, the first line of the module being
compiled is #include <stdio.h>.

Thanks for helping.
