Prototype

void  USBD_HID_OS_OutputDataPend (CPU_INT08U   class_nbr
                                  CPU_INT16U   timeout_ms,
                                  USBD_ERR    *p_err);

Arguments

class_nbr

Class instance number.

timeout_ms

Signal wait timeout in milliseconds

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 wait operation typically consists of pending on a semaphore. When the output report transfer is complete, the task is woken up by the Core layer internal task responsible for asynchronous communication. The p_err argument should be assigned as described in Table - Error code assignment according to pend operation result.
