.SH NAME
|
||
|
|
io_socketpair \- create a pair of sockets
|

|
|
.SH SYNTAX
|
||
|
|
.B #include <io.h>

|
|
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.
