It provides a set of functions used by OpenSSL for the implementation of the various \s-1BIO\s0 capabilities. See the bio page for more information. .PP \&\fBBIO_meth_new()\fR creates a new \fB\s-1BIO_METHOD\s0\fR structure. It should be given a unique integer \fBtype\fR and a string that represents its \fBname\fR. Use \fBBIO_get_new_index()\fR to get the value for \fBtype\fR. .PP The set of standard OpenSSL provided \s-1BIO\s0 types is provided in \fBbio.h\fR. Some examples include \fB\s-1BIO_TYPE_BUFFER\s0\fR and \fB\s-1BIO_TYPE_CIPHER\s0\fR. Filter BIOs should have a type which have the \*(L"filter\*(R" bit set (\fB\s-1BIO_TYPE_FILTER\s0\fR). Source/sink BIOs should have the \*(L"source/sink\*(R" bit set (\fB\s-1BIO_TYPE_SOURCE_SINK\s0\fR). File descriptor based BIOs (e.g. socket, fd, connect, accept etc) should additionally have the \&\*(L"descriptor\*(R" bit set (\fB\s-1BIO_TYPE_DESCRIPTOR\s0\fR). See the BIO_find_type page for more information. .PP \&\fBBIO_meth_free()\fR destroys a \fB\s-1BIO_METHOD\s0\fR structure and frees up any memory associated with it. .PP \&\fBBIO_meth_get_write_ex()\fR and \fBBIO_meth_set_write_ex()\fR get and set the function used for writing arbitrary length data to the \s-1BIO\s0 respectively. This function will be called in response to the application calling \fBBIO_write_ex()\fR or \&\fBBIO_write()\fR. The parameters for the function have the same meaning as for \&\fBBIO_write_ex()\fR. Older code may call \fBBIO_meth_get_write()\fR and \&\fBBIO_meth_set_write()\fR instead. Applications should not call both \&\fBBIO_meth_set_write_ex()\fR and \fBBIO_meth_set_write()\fR or call \fBBIO_meth_get_write()\fR when the function was set with \fBBIO_meth_set_write_ex()\fR. .PP \&\fBBIO_meth_get_read_ex()\fR and \fBBIO_meth_set_read_ex()\fR get and set the function used for reading arbitrary length data from the \s-1BIO\s0 respectively. This function will be called in response to the application calling \fBBIO_read_ex()\fR or \fBBIO_read()\fR. The parameters for the function have the same meaning as for \fBBIO_read_ex()\fR. Older code may call \fBBIO_meth_get_read()\fR and \fBBIO_meth_set_read()\fR instead. Applications should not call both \fBBIO_meth_set_read_ex()\fR and \fBBIO_meth_set_read()\fR or call \fBBIO_meth_get_read()\fR when the function was set with \&\fBBIO_meth_set_read_ex()\fR. .PP \&\fBBIO_meth_get_puts()\fR and \fBBIO_meth_set_puts()\fR get and set the function used for writing a \s-1NULL\s0 terminated string to the \s-1BIO\s0 respectively. This function will be called in response to the application calling \fBBIO_puts()\fR. The parameters for the function have the same meaning as for \fBBIO_puts()\fR. .PP \&\fBBIO_meth_get_gets()\fR and \fBBIO_meth_set_gets()\fR get and set the function typically used for reading a line of data from the \s-1BIO\s0 respectively (see the \fBBIO_gets\fR\|(3) page for more information). This function will be called in response to the application calling \fBBIO_gets()\fR. The parameters for the function have the same meaning as for \fBBIO_gets()\fR. .PP \&\fBBIO_meth_get_ctrl()\fR and \fBBIO_meth_set_ctrl()\fR get and set the function used for processing ctrl messages in the \s-1BIO\s0 respectively. See the BIO_ctrl page for more information. This function will be called in response to the application calling \fBBIO_ctrl()\fR. The parameters for the function have the same meaning as for \&\fBBIO_ctrl()\fR. .PP \&\fBBIO_meth_get_create()\fR and \fBBIO_meth_set_create()\fR get and set the function used for creating a new instance of the \s-1BIO\s0 respectively. This function will be called in response to the application calling \fBBIO_new()\fR and passing in a pointer to the current \s-1BIO_METHOD.\s0 The \fBBIO_new()\fR function will allocate the memory for the new \s-1BIO,\s0 and a pointer to this newly allocated structure will be passed as a parameter to the function. .PP \&\fBBIO_meth_get_destroy()\fR and \fBBIO_meth_set_destroy()\fR get and set the function used for destroying an instance of a \s-1BIO\s0 respectively. This function will be called in response to the application calling \fBBIO_free()\fR. A pointer to the \s-1BIO\s0 to be destroyed is passed as a parameter. The destroy function should be used for \s-1BIO\s0 specific clean up. The memory for the \s-1BIO\s0 itself should not be freed by this function. .PP \&\fBBIO_meth_get_callback_ctrl()\fR and \fBBIO_meth_set_callback_ctrl()\fR get and set the function used for processing callback ctrl messages in the \s-1BIO\s0 respectively. See the \fBBIO_callback_ctrl\fR\|(3) page for more information. This function will be called in response to the application calling \fBBIO_callback_ctrl()\fR. The parameters for the function have the same meaning as for \fBBIO_callback_ctrl()\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBIO_get_new_index()\fR returns the new \s-1BIO\s0 type value or \-1 if an error occurred. .PP BIO_meth_new(int type, const char *name) returns a valid \fB\s-1BIO_METHOD\s0\fR or \s-1NULL\s0 if an error occurred. .PP The \fBBIO_meth_set\fR functions return 1 on success or 0 on error. .PP The \fBBIO_meth_get\fR functions return the corresponding function pointers. .SH "SEE ALSO" .IX Header "SEE ALSO" bio, BIO_find_type, BIO_ctrl, BIO_read_ex, BIO_new .SH "HISTORY" .IX Header "HISTORY" The functions described here were added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2018 The OpenSSL Project Authors.
