Constructor & Destructor Documentation

UnixSocketSyscalls::~UnixSocketSyscalls ( )

virtual

Todo:

should shutdown() which should wake up recv() or poll()

Definition at line 1525 of file net-syscalls.cc.

Member Function Documentation

int UnixSocketSyscalls::bind ( const struct sockaddr *  address, socklen_t  addrlen  )

virtual

Todo:

unbind existing socket if one exists.

Todo:

re-bind an unnamed address if we are bound already

Todo:

does this actually create a findable file?

Todo:

errno?

Implements NetworkSyscalls.

Definition at line 1761 of file net-syscalls.cc.

References Directory::addEphemeralFile(), create(), String::endswith(), FileDescriptor::fd, VFS::find(), Directory::fromFile(), File::getFullPath(), File::getName(), VFS::instance(), File::isDirectory(), and FileDescriptor::networkImpl.

int UnixSocketSyscalls::connect ( const struct sockaddr *  address, socklen_t  addrlen  )

virtual

Todo:

wrong error

Implements NetworkSyscalls.

Definition at line 1547 of file net-syscalls.cc.

References VFS::find(), Network::getType(), VFS::instance(), and File::isSocket().

int UnixSocketSyscalls::listen ( int  backlog )

virtual

Todo:

bind to an unnamed socket if we aren't already bound

Implements NetworkSyscalls.

Definition at line 1747 of file net-syscalls.cc.

bool UnixSocketSyscalls::pairWith

(

UnixSocketSyscalls *

other

)

Pair two UnixSocketSyscalls objects such that the referenced sockets directly communicate with each other.

Definition at line 2067 of file net-syscalls.cc.

References Network::getType().

ssize_t UnixSocketSyscalls::recvfrom_msg ( struct msghdr *  msghdr )

virtual

Todo:

get info from the socket about things like truncated buffer

Todo:

except that it could be.. need to detect shutdown()

Implements NetworkSyscalls.

Definition at line 1700 of file net-syscalls.cc.

ssize_t UnixSocketSyscalls::sendto_msg ( const struct msghdr *  msghdr )

virtual

Todo:

this doesn't handle a connection going away - only a connection not being made in the first place (I think it's a different errno)

Todo:

errno

Todo:

needs some sort of errno here

Todo:

wrong error

Todo:

except that it could be.. need to detect shutdown()

Implements NetworkSyscalls.

Definition at line 1606 of file net-syscalls.cc.

References VFS::find(), Network::getType(), VFS::instance(), File::isSocket(), and File::write().

int UnixSocketSyscalls::shutdown ( int  how )

virtual

Todo:

Reimplemented from NetworkSyscalls.

Definition at line 1904 of file net-syscalls.cc.
