.SH SINOPSIS

.B #include <sys/socket.h>
.sp
.BI "int bind(int " sockfd ", struct sockaddr *" my_addr ", int " addrlen );
.SH DESCRIPCIN
.B bind
da al zcalo
.IR sockfd ,
la direccin local
.IR my_addr .
.I my_addr
tiene una longitud de
.I addrlen
bytes.  Tradicionalmente, esto se conoce como "asignar un nombre a un
zcalo"
(cuando un interruptor se crea con
.BR socket (2),
existe en un espacio de nombres (familia de direcciones) pero carece 
de nombre).
.SH NOTAS
Enlazando un nombre en el dominio UNIX crea un zcalo en el sistema
de ficheros que debe ser borrado por el invocador cuando ya no
es necesario (usando
.BR unlink (2)).

comunicacion.  Consultese las entradas en la seccin 4 para ms

el valor regresado y a
.I errno
se  le asigna un valor apropiado.
.SH ERRORES
.TP 0.8i
.B EBADF
.I sockfd
no es un descriptor vlido.
.TP
.B EINVAL

.PP
Los siguientes errores son especficos a los zcalos del dominio

La direccin
.I addr_len
es incorrecta, o el zcalo no pertenecia a la familia
.B AF_UNIX.
.TP
.B EROFS

.B ENAMETOOLONG
.I my_addr
es demasiado larga.
