1=pod 2 3=head1 NAME 4 5BIO_s_socket, BIO_new_socket - socket BIO 6 7=head1 SYNOPSIS 8 9 #include <openssl/bio.h> 10 11 const BIO_METHOD *BIO_s_socket(void); 12 13 BIO *BIO_new_socket(int sock, int close_flag); 14 15=head1 DESCRIPTION 16 17BIO_s_socket() returns the socket BIO method. This is a wrapper 18round the platform's socket routines. 19 20BIO_read_ex() and BIO_write_ex() read or write the underlying socket. 21BIO_puts() is supported but BIO_gets() is not. 22 23If the close flag is set then the socket is shut down and closed 24when the BIO is freed. 25 26BIO_new_socket() returns a socket BIO using B<sock> and B<close_flag>. 27 28=head1 NOTES 29 30Socket BIOs also support any relevant functionality of file descriptor 31BIOs. 32 33The reason for having separate file descriptor and socket BIOs is that on some 34platforms sockets are not file descriptors and use distinct I/O routines, 35Windows is one such platform. Any code mixing the two will not work on 36all platforms. 37 38=head1 RETURN VALUES 39 40BIO_s_socket() returns the socket BIO method. 41 42BIO_new_socket() returns the newly allocated BIO or NULL is an error 43occurred. 44 45=head1 COPYRIGHT 46 47Copyright 2000-2016 The OpenSSL Project Authors.
