SSL_CONF_cmd_argv - SSL configuration command line processing
|
|
=head1 SYNOPSIS
|
|
#include <openssl/ssl.h>
|
|
int SSL_CONF_cmd_argv(SSL_CONF_CTX *cctx, int *pargc, char ***pargv);
|
|
=head1 DESCRIPTION
|
|
The function SSL_CONF_cmd_argv() processes at most two command line
|
arguments from B<pargv> and B<pargc>. The values of B<pargv> and B<pargc>
|
are updated to reflect the number of command options processed. The B<pargc>
|
argument can be set to B<NULL> if it is not used.
|
|
=head1 RETURN VALUES
|
|
SSL_CONF_cmd_argv() returns the number of command arguments processed: 0, 1, 2
|
or a negative error code.
|
|
If -2 is returned then an argument for a command is missing.
|
|
If -1 is returned the command is recognised but couldn't be processed due
|
to an error: for example a syntax error in the argument.
