SysV message queue

SysV message queue

QNX POSIX message queue (mqueue server or mq server/library)

Using the SBIO_MQ_PATH environment variable you can determine which message queue technology will be used. By default the standard mqueue server and corresponding C library mq_* functions will be used.

If the SBIO_MQ_PATH environment variable is set to point at the libmq.so library (i.e. SBIO_MQ_PATH=/usr/lib/libmq.so) then the default binding for the message queue implementation can be changed to use the mq server and the corresponding mq library functions.

If the SBIO_MQ_PATH environment variable is used, then it must be used consistently with all Storyboard IO clients and servers that want to communicate with one another.
