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);
