DESCRIPTION:

This directive creates a extension set. The assigned extension set id is returned in id. This id is used to access the extension set with other user extension manager directives. For control and maintenance of the extension set, RTEMS allocates an ESCB from the local ESCB free pool and initializes it.

NOTES:

This directive will not cause the calling task to be preempted.
