NAME

       explain_statvfs_or_die - get file system statistics and report errors

SYNOPSIS

       #include <libexplain/statvfs.h>
       void explain_statvfs_or_die(const char *pathname, struct statvfs *data);
       int explain_statvfs_on_error(const char *pathname, struct statvfs *data);

DESCRIPTION

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

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

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

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

RETURN VALUE

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

       The explain_statvfs_on_error function always returns  the  value  return  by  the  wrapped
       statvfs(2) system call.

EXAMPLE

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