Structure for requesting a hardware-protected memory buffer

Fields

hdr: MMAL_PARAMETER_HEADER_T

size_wanted: u32

< Input. Zero size means internal video decoder buffer, mem_handle and phys_addr not returned in this case

protect: u32

< Input. 1 = protect, 0 = unprotect

mem_handle: u32

< Output. Handle for protected buffer

phys_addr: *mut c_void

< Output. Physical memory address of protected buffer
