Prototype

void  USBD_HID_OS_InputDataPend (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

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