.TH io_socketpair 3 .SH NAME io_socketpair \- create a pair of sockets .SH SYNTAX .B #include int \fBio_socketpair\fP(int64 pfd[2]); .SH DESCRIPTION io_socketpair creates a new UNIX socket pair and writes both descriptors to \fId\fR. The socket pair works much like a pipe, but it is bidirectional (i.e. both descriptors are for reading and writing). io_socketpair returns 1 to indicate success. If something goes wrong, io_socketpair returns 0, setting errno to indicate the error; in this case it frees any memory that it allocated for the new socketpair, and it leaves \fId\fR alone. .SH "SEE ALSO" io_readfile(3), io_createfile(3), io_pipe(3)
