SysTaskSetPriority

This function of type BOOL can be used to define the priority level for a task which is identified by the task Id. TRUE will be returned in case of a successful operation, otherwise FALSE.

The priority level can be a value between 0 (=highest priority ) and 255 (=lowest priority ).

Note

SysTask functions are not reentrant. This should be no problem in normal cases, but if in the application program a situation might occur, where several IEC-tasks create and manage additional tasks, the calls to these functions have to be synchronized. You can use the library The Library SysLibSem.lib in this case.
