os_sem_init

#include <rtl.h>

void os_sem_init (
    OS_ID semaphore,        /* The semaphore object to initialize */
    U16   token_count );    /* Initial number of tokens */

The os_sem_init function initializes the semaphore object identified by the function argument.

The argument token_count determines the number of tokens stored in the semaphore initially.

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

Note

• You must define the semaphore object of type OS_SEM. You can use the name of the semaphore object to identify it during operation.

The os_sem_init function does not return any value.
