Prototype

void  USBD_PHDC_RdCfg (CPU_INT08U           class_nbr,
                       LATENCY_RELY_FLAGS   latency_rely,
                       CPU_INT08U          *p_data_opaque,

USBD_PHDC_LATENCY_HIGH_RELY_BEST

USBD_PHDC_LATENCY_MEDIUM_RELY_BEST

p_data_opaque

Pointer to a buffer that contains opaque data related to this communication pipe.

data_opaque_len

Length of opaque data (in octets). If 0, no metadata descriptor will be written for the endpoint.

p_err

USBD_ERR_NONE

USBD_ERR_NULL_PTR

USBD_ERR_INVALID_ARG

Returned Value

None.

Callers
