Modules

descriptor

fcntl 🔒

file_flags 🔒

file_traits

FileReadWriteAtVolatile is implemented in terms of pread and pwrite. These are provided by platform-specific imports. On Linux they resolve to the 64-bit versions, while on MacOS the base versions are already 64-bit.

handle_eintr

Macro and helper trait for handling interrupted routines.

iobuf 🔒

net

sock_ctrl_msg 🔒

Used to send and receive messages with file descriptors on sockets that accept control messages (e.g. Unix domain sockets).

Structs

ScmSocket

Trait for file descriptors can send and receive socket control messages via sendmsg and recvmsg.

StreamChannel

An abstraction over named pipes and unix socketpairs. This abstraction can be used in a blocking and non blocking mode.

Enums

BlockingMode

FileFlags

FramingMode

Constants

SCM_MAX_FD

SCM_SOCKET_MAX_FD_COUNT

The maximum number of FDs that can be sent in a single send.

Traits

AsIobuf

Trait for types that can be converted into an iovec that can be referenced by a syscall for the lifetime of this object.

Functions

add_fd_flags

Performs a logical OR of the given flags with the FD’s flags, setting the given bits for the FD.

clear_fd_flags

Clears the given flags in the FD’s flags.

duration_to_timespec

Return a timespec filed with the specified Duration duration.

Type Aliases

IoBuf

Cross platform binary compatible iovec. See crate::IoBufMut for documentation.

Pid

Process identifier.
