Expand description

Structure used for storage of ancillary data object information.

Fields

cmsg_len: usize

Length of data in cmsg_data plus length of cmsghdr structure. The type should be socklen_t but the definition of the kernel is incompatible with this.

cmsg_level: c_int

Originating protocol.

cmsg_type: c_int

Protocol specific type.

__cmsg_data: __IncompleteArrayField<c_uchar>

Ancillary data.
