Function Documentation

int explain_pipe_on_error

(

int *

pipefd

)

The explain_pipe_on_error function is used to call the pipe(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_pipe(3) function.

This function is intended to be used in a fashion similar to the following example:

 if (explain_pipe_on_error(pipefd) < 0)
 {
     ...cope with error
     ...no need to print error message
 }

Parameters:

pipefd

The pipefd, exactly as to be passed to the pipe(2) system call.

Returns:

The value returned by the wrapped pipe(2) system call.
