isr_send_signal

Summary	#include <rtx166t.h> int isr_send_signal ( int task_id); /* Task to signal */
Description	The isr_send_signal function sends a signal to task task_id. If the specified task is already waiting for a signal, this function readies the task for execution but does not start it. Otherwise, the signal is stored in the signal flag of the task. Note This function is part of the RTX166 Tiny Real-Time Operating System. This function may be called only from interrupt functions.
Return Value	The isr_send_signal function returns a value of 0 if the signal was set successfully, a value of 1 if the signal was already set, and a value of -1 if the specified task does not exist.
