- #shmctl ID,CMD,ARG
-
Calls the System V IPC function shmctl. You'll probably have to say
use IPC::SysV;first to get the correct constant definitions. If CMD is
IPC_STAT, then ARG must be a variable that will hold the returnedshmid_dsstructure. Returns like ioctl:undeffor error; "0but true" for zero; and the actual return value otherwise. See also "SysV IPC" in perlipc and the documentation forIPC::SysV.Portability issues: "shmctl" in perlport.
