tsk_lock

#include <rtl.h>

void tsk_lock (void);

The tsk_lock function disables the RTX kernel timer interrupts and thereby disables task switching.

The tsk_lock function is in the RL-RTX library. The prototype is defined in rtl.h.

Note

• Nested calls of the function tsk_lock are not supported.
• Calling the function tsk_lock from an interrupt handler is not allowed.
• For the duration when timer interrupts are disabled, the RTX kernel task scheduler and Round Robin task scheduling is blocked, and timeouts do not work. Hence, it is highly recommended to disable RTX kernel timer interrupts only for a very short time period.
