CONF_modules_free(3) OpenSSL CONF_modules_free(3) NAME CONF_modules_free, CONF_modules_finish, CONF_modules_unload - OpenSSL configuration cleanup functions LIBRARY libcrypto, -lcrypto SYNOPSIS #include <openssl/conf.h> void CONF_modules_free(void); void CONF_modules_finish(void); void CONF_modules_unload(int all); DESCRIPTION CONF_modules_free() closes down and frees up all memory allocated by all configuration modules. CONF_modules_finish() calls each configuration modules finish handler to free up any configuration that module may have performed. CONF_modules_unload() finishes and unloads configuration modules. If all is set to 0 only modules loaded from DSOs will be unloads. If all is 1 all modules, including builtin modules will be unloaded. NOTES Normally applications will only call CONF_modules_free() at application to tidy up any configuration performed. RETURN VALUE None of the functions return a value.
