Struct cmsghdr

#[repr(C)]pub struct cmsghdr {
    pub cmsg_len: usize,
    pub cmsg_level: c_int,
    pub cmsg_type: c_int,
    pub __cmsg_data: __IncompleteArrayField<c_uchar>,
}

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.
