83 =1 * Description: This function is called by other uC/OS-II services and is used to ready a task that was
84 =1 * waiting for an event to occur.
85 =1 *
86 =1 * Arguments : pevent is a pointer to the event control block corresponding to the event.
87 =1 *
88 =1 * msg is a pointer to a message. This pointer is used by message oriented services
89 =1 * such as MAILBOXEs and QUEUEs. The pointer is not used when called by other
90 =1 * service functions.
91 =1 *
92 =1 * msk is a mask that is used to clear the status byte of the TCB. For example,
93 =1 * OSSemPost() will pass OS_STAT_SEM, OSMboxPost() will pass OS_STAT_MBOX etc.
94 =1 *
95 =1 * Returns : none
96 =1 *
97 =1 * Note : This function is INTERNAL to uC/OS-II and your application should not call it.
