This is a wrapper +round the platform's socket routines. + +BIO_read() and BIO_write() read or write the underlying socket. +BIO_puts() is supported but BIO_gets() is not. + +If the close flag is set then the socket is shut down and closed +when the BIO is freed. + +BIO_set_fd() sets the socket of BIO B<b> to B<fd> and the close +flag to B<close_flag>. + +BIO_get_fd() places the socket in B<c> if it is not NULL, it also +returns the socket. If B<c> is not NULL it should be of type (int *). + +BIO_new_socket() returns a socket BIO using B<sock> and B<close_flag>. + +=head1 NOTES + +Socket BIOs also support any relevant functionality of file descriptor +BIOs. + +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. + +BIO_set_fd() and BIO_get_fd() are macros. + +=head1 RETURN VALUES + +BIO_s_socket() returns the socket BIO method. + +BIO_set_fd() always returns 1. + +BIO_get_fd() returns the socket or -1 if the BIO has not been +initialized. + +BIO_new_socket() returns the newly allocated BIO or NULL is an error +occurred. + +=head1 SEE ALSO + +TBA |
