This is a wrapper round the platform's socket routines. .PP \&\fBBIO_read()\fR and \fBBIO_write()\fR read or write the underlying socket. \&\fBBIO_puts()\fR is supported but \fBBIO_gets()\fR is not. .PP If the close flag is set then the socket is shut down and closed when the \s-1BIO\s0 is freed. .PP \&\fBBIO_set_fd()\fR sets the socket of \s-1BIO\s0 \fBb\fR to \fBfd\fR and the close flag to \fBclose_flag\fR. .PP \&\fBBIO_get_fd()\fR places the socket in \fBc\fR if it is not \s-1NULL,\s0 it also returns the socket. If \fBc\fR is not \s-1NULL\s0 it should be of type (int *). .PP \&\fBBIO_new_socket()\fR returns a socket \s-1BIO\s0 using \fBsock\fR and \fBclose_flag\fR. .SH "NOTES" .IX Header "NOTES" Socket BIOs also support any relevant functionality of file descriptor BIOs. .PP The reason for having separate file descriptor and socket BIOs is that on some platforms sockets are not file descriptors and use distinct I/O routines, Windows is one such platform. Any code mixing the two will not work on all platforms. .PP \&\fBBIO_set_fd()\fR and \fBBIO_get_fd()\fR are macros. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBIO_s_socket()\fR returns the socket \s-1BIO\s0 method. .PP \&\fBBIO_set_fd()\fR always returns 1. .PP \&\fBBIO_get_fd()\fR returns the socket or \-1 if the \s-1BIO\s0 has not been initialized. .PP \&\fBBIO_new_socket()\fR returns the newly allocated \s-1BIO\s0 or \s-1NULL\s0 is an error occurred. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\s-1TBA\s0
