SYNOPIS

This defines the control structures needed for the RW routines. The function prototypes for the non-inlined versions are defined in a separate file, since they do not depend on the structure definitions.

This file is automatically included with the file RW.h

Typedef Documentation

RW_waitctl_bf

Typedef for union _RW_waitctl_bf.

The low 31 bits of the wait control word are used as a count of the number of pending tasks. The sign bit is used as an enable/disable flag. If the flag is disabled (set), RW_wake will not generate a signal to wake up any pending tasks.
