Hello -
I am a total newbie C programmer on z/OS. I took what seemed to be a simple C program to get my feet wet with using the C compiler on z/OS. The sample program is supposedly written in K&R standard C. However, when I try to compile it I get the following errors. Below is a snippet of the include files along with the errors flagged by the compiler. It seems that I may be missing one or more includes that contain the definition of "timeval" and "optarg", but I cannot find where they would be. Any help that you can offer to resolve these errors would be greatly appreciated. Thanks.
Regards,
Perry Shindle
