NAME

msgctl - SysV IPC message control operations


SYNOPSIS

msgctl ID,CMD,ARG


DESCRIPTION

Calls the System V IPC function msgctl(2). 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 which will hold the returned msqid_ds structure. Returns like ioctl(): the undefined value for error, ``0 but true'' for zero, or the actual return value otherwise. See also IPC::SysV and IPC::Semaphore::Msg documentation.


DISCLAIMER

We are painfully aware that these documents may contain incorrect links and misformatted HTML. Such bugs lie in the automatic translation process that automatically created the hundreds and hundreds of separate documents that you find here. Please do not report link or formatting bugs, because we cannot fix per-document problems. The only bug reports that will help us are those that supply working patches to the installhtml or pod2html programs, or to the Pod::HTML module itself, for which I and the entire Perl community will shower you with thanks and praises.

If rather than formatting bugs, you encounter substantive content errors in these documents, such as mistakes in the explanations or code, please use the perlbug utility included with the Perl distribution.
