#pragma fncall main MyTask
void MyTask (void)

Call allowed:

priority Task priority. Allowed values from 0 (highest) to 7 (lowest).
TaskName Name of C-function to be used as task


bError If there is no free descriptor to create task then OS_IsError will return true


void Task1 (void)
    for (;;) OS_Yield();
void Task2 (void)
    for (;;) OS_Yield();
void main (void)
    OS_Task_Create(1, Task1);    // Create task Task1 with priority 1
    OS_Task_Create(5, Task2);    // Create task Task2 with priority 5
