NAME

       explain_statfs_or_die - get file system statistics and report errors

SYNOPSIS

       #include <libexplain/statfs.h>
       void explain_statfs_or_die(const char *pathname, struct statfs *data);
       int explain_statfs_on_error(const char *pathname, struct statfs *data);

DESCRIPTION

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

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

       pathname
               The pathname, exactly as to be passed to the  statfs(2)  system
               call.

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

RETURN VALUE

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

       The explain_statfs_on_error function always returns the value return by
       the wrapped statfs(2) system call.

EXAMPLE

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