NAME

       explain_mount_or_die - mount file system and report errors

SYNOPSIS

       #include <libexplain/mount.h>
       void   explain_mount_or_die(const   char   *source,   const   char   *target,  const  char
       *file_systems_type, unsigned long flags, const void *data);
       int  explain_mount_on_error(const  char  *source,   const   char   *target,   const   char
       *file_systems_type, unsigned long flags, const void *data);

DESCRIPTION

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

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

       source  The source, exactly as to be passed to the mount(2) system call.

       target  The target, exactly as to be passed to the mount(2) system call.

       file_systems_type
               The file_systems_type, exactly as to be passed to the mount(2) system call.

       flags   The flags, exactly as to be passed to the mount(2) system call.

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

RETURN VALUE

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

       The explain_mount_on_error function  always  returns  the  value  return  by  the  wrapped
       mount(2) system call.

EXAMPLE

       The  explain_mount_or_die  function  is  intended  to  be used in a fashion similar to the
       following example:
              explain_mount_or_die(source, target, file_systems_type, flags, data);

       explain_mount(3)

       exit(2) terminate the calling process
