-.SH NAME
-ftok \- convert a pathname and a project identifier to a System V IPC key
-.SH LIBRARY
-Standard C library
-.RI ( libc ", " \-lc )
-.SH SYNOPSIS
-.nf
-.B #include <sys/ipc.h>
-.fi
-.P
-.BI "key_t ftok(const char *" pathname ", int " proj_id );
-.SH DESCRIPTION
-The
-.BR ftok ()
-function uses the identity of the file named by the given
-.I pathname
-(which must refer to an existing, accessible file)
-and the least significant 8 bits of
-.I proj_id
-(which must be nonzero) to generate a
-.I key_t
-type System V IPC key, suitable for use with
-.BR msgget (2),
-.BR semget (2),
-or
-.BR shmget (2).
-.P
-The resulting value is the same for all pathnames that
-name the same file, when the same value of
-.I proj_id
-is used.
-The value returned should be different when the
-(simultaneously existing) files or the project IDs differ.
-.SH RETURN VALUE
-On success, the generated
-.I key_t
-value is returned.
-On failure \-1 is returned, with
-.I errno
-indicating the error as for the
-.BR stat (2)
-system call.
-.SH ATTRIBUTES
-For an explanation of the terms used in this section, see
-.BR attributes (7).

-.SH HISTORY
-POSIX.1-2001.
-.SH NOTES
-On some ancient systems, the prototype was:
-.P
-.in +4n
-.EX
-.BI "key_t ftok(char *" pathname ", char " proj_id );
-.EE
-.in
-.P
-Today,
-.I proj_id
-is an
-.IR int ,
-but still only 8 bits are used.
-Typical usage has an ASCII character
-.IR proj_id ,
-that is why the behavior is said to be undefined when
-.I proj_id
-is zero.
-.P
-Of course, no guarantee can be given that the resulting
-.I key_t
-is unique.
-Typically, a best-effort attempt combines the given
-.I proj_id
-byte, the lower 16 bits of the inode number, and the
-lower 8 bits of the device number into a 32-bit result.
-Collisions may easily happen, for example between files on
-.I /dev/hda1
-and files on
-.IR /dev/sda1 .

-See
-.BR semget (2).
