NAME

       explain_fstatfs_or_die - get file system statistics and report errors

SYNOPSIS

       #include <libexplain/fstatfs.h>
       void explain_fstatfs_or_die(int fildes, struct statfs *data);
       int explain_fstatfs_on_error(int fildes, struct statfs *data);

DESCRIPTION

       The explain_fstatfs_or_die function is used to call the fstatfs(2) system call. On failure
       an explanation will be printed to stderr, obtained from the  explain_fstatfs(3)  function,
       and then the process terminates by calling exit(EXIT_FAILURE).

       The  explain_fstatfs_on_error  function  is  used  to  call the fstatfs(2) system call. On
       failure an explanation will be printed to stderr,  obtained  from  the  explain_fstatfs(3)
       function, but still returns to the caller.

       fildes  The fildes, exactly as to be passed to the fstatfs(2) system call.

       data    The data, exactly as to be passed to the fstatfs(2) system call.

RETURN VALUE

       The  explain_fstatfs_or_die  function  only  returns  on  success, see fstatfs(2) for more
       information. On failure, prints an explanation and exits, it does not return.

       The explain_fstatfs_on_error function always returns  the  value  return  by  the  wrapped
       fstatfs(2) system call.

EXAMPLE

       The  explain_fstatfs_or_die  function  is  intended to be used in a fashion similar to the
       following example:
              explain_fstatfs_or_die(fildes, data);
