-.Dd June 24, 1994
-.Os
-.Dt ftok 3
-.Sh NAME
-.Nm ftok
-.Nd create IPC identifier from path name
-.Sh SYNOPSIS
-.Fd #include <sys/types.h>
-.Fd #include <sys/ipc.h>
-.Ft key_t
-.Fn ftok "const char *path" "int id"
-.Sh DESCRIPTION
-.Bf -symbolic
-This function is available from the compatibility library, libcompat.
-.Ef
-The
-.Fn ftok
-function attempts to create a unique key suitable for use with the
-.Xr msgget 3 ,
-.Xr semget 2
-and
-.Xr shmget 2
-functions given the
-.Fa path
-of an existing file and a user-selectable
-.Fa id .
-.Pp
-The specified
-.Fa path
-must specify an existing file that is accessible to the calling process
-or the call will fail.  Also, note that links to files will return the
-same key, given the same
-.Fa id .
-.Sh RETURN VALUES
-The
-.Fn ftok
-function will return -1 if
-.Fa path
-does not exist or if it cannot be accessed by the calling process.
-.Sh SEE ALSO
-.Xr semget 2 ,
-.Xr shmget 2 ,
-.Xr msgget 3
-.Sh HISTORY
-The
-.Fn ftok
-function originates with System V and is typically used by programs
-that use the System V IPC routines.
-.Sh AUTHORS
-.An Thorsten Lockert Aq tholo@sigmasoft.com
-.Sh BUGS
-The returned key is computed based on the device minor number and inode of the
-specified
-.Fa path
-in combination with the lower 8 bits of the given
-.Fa id .
-Thus it is quite possible for the routine to return duplicate keys.
