<function>shm_attach</function> returns an id that can be used to access

the System V shared memory with the given <parameter>key</parameter>, the

A second call to <function>shm_attach</function> for the same

identifier, but both identifiers access the same underlying

shared memory. <parameter>memsize</parameter> and

<parameter>perm</parameter> will be ignored.
