os_sys_init_prio

#include <rtl.h>

void os_sys_init_prio (
    void (*task)(void),   /* Task to start */
    U8 priority);         /* Task priority (1-254) */

The os_sys_init_prio function initializes and starts the Real-Time eXecutive (RTX) kernel.

The task argument points to the task to start after the kernel is initialized.

The priority argument specifies the priority for the task. The default task priority is 1. Priority 0 is reserved for the Idle Task. If a value of 0 is specified for the priority, it is automatically replaced with a value of 1. Priority 255 is also reserved.

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

Note

• The os_sys_init_prio function must be called from the main C function.
• The RTK kernel uses the default stack size, which is defined in rtx_config.c, for the task.
• Priority value of 255 represents the most important task.

The os_sys_init_prio function does not return. Program execution continues with the task identified by the task argument.
