PIPE(2) Example Does Not Compile

PIPE(2) Example Does Not Compile

[-- Attachment #1: Type: text/plain, Size: 658 bytes --]

Dear man-page maintainers,

I believe I found a bug in the PIPE(2) example code.

When trying to compile the example code, the following error was thrown:

    pipes.c: In function ‘main’:
    pipes.c:10:5: error: unknown type name ‘pid_t’
         pid_t cpid;
         ^
After adding the line:

    #include <sys/types.h>

The example compiled fine.

I compiled with:

    gcc -Wall -std=c99

Attached is a patch that append the line to include sys/types.h.

manpage-version: 3.54-1
gcc-version: gcc (Debian 4.8.2-1) 4.8.2

Let me know if you need any more info, or if this is not truly a bug.

Thank you,
-- Trevor Bramwell

Michael,

Yes you did. I sent it twice as the first time I did not CC the correct lists.
