+.IP "ftok( PATH )" 4
+.IX Item "ftok( PATH )"
+.PD 0
+.IP "ftok( PATH, ID )" 4
+.IX Item "ftok( PATH, ID )"
+.PD
+Return a key based on PATH and ID, which can be used as a key for
+\&\f(CW\*(C`msgget\*(C'\fR, \f(CW\*(C`semget\*(C'\fR and \f(CW\*(C`shmget\*(C'\fR. See \fBftok\fR\|(3).
+.Sp
+If ID is omitted, it defaults to \f(CW1\fR. If a single character is
+given for ID, the numeric value of that character is used.
+.IP "shmat( ID, ADDR, FLAG )" 4
+.IX Item "shmat( ID, ADDR, FLAG )"
+Attach the shared memory segment identified by ID to the address
+space of the calling process. See \fBshmat\fR\|(2).
+.Sp
+ADDR should be \f(CW\*(C`undef\*(C'\fR unless you really know what you're doing.
+.IP "shmdt( ADDR )" 4
+.IX Item "shmdt( ADDR )"
+Detach the shared memory segment located at the address specified
+by ADDR from the address space of the calling process. See \fBshmdt\fR\|(2).
+.IP "memread( ADDR, VAR, POS, SIZE )" 4
+.IX Item "memread( ADDR, VAR, POS, SIZE )"
+Reads SIZE bytes from a memory segment at ADDR starting at position POS.
+VAR must be a variable that will hold the data read. Returns true if
+successful, or false if there is an error. \fBmemread()\fR taints the variable.
+.IP "memwrite( ADDR, STRING, POS, SIZE )" 4
+.IX Item "memwrite( ADDR, STRING, POS, SIZE )"
+Writes SIZE bytes from STRING to a memory segment at ADDR starting at
+position POS. If STRING is too long, only SIZE bytes are used; if STRING
+is too short, nulls are written to fill out SIZE bytes. Returns true if
+successful, or false if there is an error.
