<para>

<function>shm_attach</function> returns an id that that can be
|
|
used to access the System V shared memory with the given key, the
|
|
first call creates the shared memory segment with <parameter>memsize</parameter>
|
|
(default: sysvshm.init_mem in the &php.ini;, otherwise
|
|
10000 bytes) and the optional perm-bits <parameter>perm</parameter>
|
|
(default: 0666).

</para>
|

<para>
|
|
A second call to <function>shm_attach</function> for the same
|
|
<parameter>key</parameter> will return a different shared memory
|
|
identifier, but both identifiers access the same underlying
|
|
shared memory. <parameter>Memsize</parameter> and
|
|
<parameter>perm</parameter> will be ignored.
