NAME

6       explain_pipe2_or_die - create pipe and report errors
7

SYNOPSIS

9       #include <libexplain/pipe2.h>
10       void explain_pipe2_or_die(int *fildes, int flags);
11       int explain_pipe2_on_error(int *fildes, int flags);

DESCRIPTION

14       The  explain_pipe2_or_die  function is used to call the pipe2(2) system
15       call. On failure an explanation will be  printed  to  stderr,  obtained
16       from  the explain_pipe2(3) function, and then the process terminates by
17       calling exit(EXIT_FAILURE).
18
19       The explain_pipe2_on_error function is used to call the pipe2(2) system
20       call.  On  failure  an  explanation will be printed to stderr, obtained
21       from the explain_pipe2(3) function, but still returns to the caller.
22
23       fildes  The fildes, exactly as to be  passed  to  the  pipe2(2)  system
24               call.
25
26       flags   The flags, exactly as to be passed to the pipe2(2) system call.
27

RETURN VALUE

29       The explain_pipe2_or_die function only returns on success, see pipe2(2)
30       for more information. On failure, prints an explanation and  exits,  it
31       does not return.
32
33       The  explain_pipe2_on_error function always returns the value return by
34       the wrapped pipe2(2) system call.
35

38       similar to the following example:
39              explain_pipe2_or_die(fildes, flags);
