Synopsis
shmwrite id, string, pos, size
Description
Writes to the shared memory segment ID starting at
position pos for size size (by attaching to it, copying in, and
detaching from it). If string is too long, only size
bytes are used;
if string is too short, nulls are written to fill out size
bytes. The
function returns true if successful, or false if there is an error.
On error, it puts the error code into $!. This function is
available only on machines supporting System V IPC.
