Function hipMallocPitch

Source 
pub unsafe extern "C" fn hipMallocPitch(
    ptr: *mut *mut c_void,
    pitch: *mut usize,
    width: usize,
    height: usize,
) -> hipError_t
Expand description

Allocates at least width (in bytes) * height bytes of linear memory Padding may occur to ensure alighnment requirements are met for the given row The change in width size due to padding will be returned in *pitch. Currently the alignment is set to 128 bytes

@param[out] ptr Pointer to the allocated device memory @param[out] pitch Pitch for allocation (in bytes) @param[in] width Requested pitched allocation width (in bytes) @param[in] height Requested pitched allocation height

If size is 0, no memory is allocated, *ptr returns nullptr, and hipSuccess is returned.
