Prototype

void  USBD_HID_OS_TxLock (CPU_INT08U   class_nbr,
                          USBD_ERR    *p_err);


Arguments

class_nbr

Class instance number.

p_err

Pointer to variable that will receive the return error code from this function.

USBD_ERR_NONE: OS error code(s) relevant to failure(s).

Callers

HID Class.

Implementation Guidelines

The lock operation typically consists in pending on a semaphore. If the semaphore is free, the task continues normally its execution, otherwise it waits until another task releases the semaphore. p_err argument should be assigned as described in Table - Error code assignment according to pend operation result.
