.SH DESCRIO
A chamada
.N socketpair
cria um par, sem nome, de sockets conectados no
domnio especficado
.IR d ,
com o
.IR type ,

.IR protocol .
Os descritores usados no referenciao dos novos sockets so retornados em
.IR sv [0]
e
.IR sv [1].
Os dois sockets so indistinguveis.
.SH "VALORES RETORNADOS"
