Function hip_sys::hiprt::hipCtxEnablePeerAccess

pub unsafe extern "C" fn hipCtxEnablePeerAccess(
    peerCtx: *mut ihipCtx_t,
    flags: u32
) -> hipError_t

@brief Enables direct access to memory allocations in a peer context.

Memory which already allocated on peer device will be mapped into the address space of the current device. In addition, all future memory allocations on peerDeviceId will be mapped into the address space of the current device when the memory is allocated. The peer memory remains accessible from the current device until a call to hipDeviceDisablePeerAccess or hipDeviceReset.

@returns #hipSuccess, #hipErrorInvalidDevice, #hipErrorInvalidValue, #hipErrorPeerAccessAlreadyEnabled
