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);
