Robert Haas	d89746c7c5	Fix compiler warning. Kevin Gritter reports that his compiler complains about inq and outq being possibly-uninitialized at the point where they are passed to shm_mq_attach(). They are initialized by the call to setup_dynamic_shared_memory, but apparently his compiler is inlining that function and then having doubts about whether the for loop will always execute at least once. Fix by initializing them to NULL.	12 years ago

Robert Haas	4db3744f1f	Test code for shared memory message queue facility. This code is intended as a demonstration of how the dynamic shared memory and dynamic background worker facilities can be used to establish a group of coooperating processes which can coordinate their activities using the shared memory message queue facility. By itself, the code does nothing particularly interesting: it simply allows messages to be passed through a loop of workers and back to the original process. But it's a useful unit test, in addition to its demonstration value.	12 years ago

Fix compiler warning.

Kevin Gritter reports that his compiler complains about inq and outq
being possibly-uninitialized at the point where they are passed to
shm_mq_attach().  They are initialized by the call to
setup_dynamic_shared_memory, but apparently his compiler is inlining
that function and then having doubts about whether the for loop will
always execute at least once.  Fix by initializing them to NULL.

Test code for shared memory message queue facility.

This code is intended as a demonstration of how the dynamic shared
memory and dynamic background worker facilities can be used to establish
a group of coooperating processes which can coordinate their activities
using the shared memory message queue facility.  By itself, the code
does nothing particularly interesting: it simply allows messages to
be passed through a loop of workers and back to the original process.
But it's a useful unit test, in addition to its demonstration value.
