Expand description

Pack pointers to various structures into into msghdr

ยงSafety

iov_buffer and iov_buffer_len must point to a slice of IoSliceMut and number of available elements or be a null pointer and 0

cmsg_buffer and cmsg_capacity must point to a byte buffer used to store control headers later or be a null pointer and 0 if control headers are not used

Buffers must remain valid for the whole lifetime of msghdr
