It provides a set of of functions used by OpenSSL for the implementation +of the various BIO capabilities. See the L<bio> page for more information. + +BIO_meth_new() creates a new B<BIO_METHOD> structure. It should be given a +unique integer B<type> and a string that represents its B<name>. +Use BIO_get_new_index() to get the value for B<type>. + +The set of +standard OpenSSL provided BIO types is provided in B<bio.h>. Some examples +include B<BIO_TYPE_BUFFER> and B<BIO_TYPE_CIPHER>. Filter BIOs should have a +type which have the "filter" bit set (B<BIO_TYPE_FILTER>). Source/sink BIOs +should have the "source/sink" bit set (B<BIO_TYPE_SOURCE_SINK>). File descriptor +based BIOs (e.g. socket, fd, connect, accept etc) should additionally have the +"descriptor" bit set (B<BIO_TYPE_DESCRIPTOR>). See the L<BIO_find_type> page for +more information. + +BIO_meth_free() destroys a B<BIO_METHOD> structure and frees up any memory +associated with it. + +BIO_meth_get_write() and BIO_meth_set_write() get and set the function used for +writing arbitrary length data to the BIO respectively. This function will be +called in response to the application calling BIO_write(). The parameters for +the function have the same meaning as for BIO_write(). + +BIO_meth_get_read() and BIO_meth_set_read() get and set the function used for +reading arbitrary length data from the BIO respectively. This function will be +called in response to the application calling BIO_read(). The parameters for the +function have the same meaning as for BIO_read(). + +BIO_meth_get_puts() and BIO_meth_set_puts() get and set the function used for +writing a NULL terminated string to the BIO respectively. This function will be +called in response to the application calling BIO_puts(). The parameters for +the function have the same meaning as for BIO_puts(). + +BIO_meth_get_gets() and BIO_meth_set_gets() get and set the function typically +used for reading a line of data from the BIO respectively (see the L<BIO_gets(3)> +page for more information). This function will be called in response to the +application calling BIO_gets(). The parameters for the function have the same +meaning as for BIO_gets(). + +BIO_meth_get_ctrl() and BIO_meth_set_ctrl() get and set the function used for +processing ctrl messages in the BIO respectively. See the L<BIO_ctrl> page for +more information. This function will be called in response to the application +calling BIO_ctrl(). The parameters for the function have the same meaning as for +BIO_ctrl(). + +BIO_meth_get_create() and BIO_meth_set_create() get and set the function used +for creating a new instance of the BIO respectively. This function will be +called in response to the application calling BIO_new() and passing +in a pointer to the current BIO_METHOD. The BIO_new() function will allocate the +memory for the new BIO, and a pointer to this newly allocated structure will +be passed as a parameter to the function. + +BIO_meth_get_destroy() and BIO_meth_set_destroy() get and set the function used +for destroying an instance of a BIO respectively. This function will be +called in response to the application calling BIO_free(). A pointer to the BIO +to be destroyed is passed as a parameter. The destroy function should be used +for BIO specific clean up. The memory for the BIO itself should not be freed by +this function. + +BIO_meth_get_callback_ctrl() and BIO_meth_set_callback_ctrl() get and set the +function used for processing callback ctrl messages in the BIO respectively. See +the L<BIO_callback_ctrl(3)> page for more information. This function will be called +in response to the application calling BIO_callback_ctrl(). The parameters for +the function have the same meaning as for BIO_callback_ctrl(). + +=head1 SEE ALSO + +L<bio>, L<BIO_find_type>, L<BIO_ctrl>, L<BIO_read>, L<BIO_new> + +=head1 HISTORY + +The functions described here were added in OpenSSL version 1.1.0. + +=head1 COPYRIGHT + +Copyright 2016 The OpenSSL Project Authors.
