NCONF_new_ex()
creates a new CONF object in heap memory and assigns to
it a context libctx that can be used during loading. If the method table
meth is set to NULL then the default value of NCONF_default()
is used.
NCONF_new()
is similar to NCONF_new_ex()
but sets the libctx to NULL.
NCONF_free()
frees the data associated with conf and then frees the conf
object.
NCONF_load()
parses the file named filename and adds the values found to
conf. If an error occurs file and eline list the file and line that
the load failed on if they are not NULL.
NCONF_default()
gets the default method table for processing a configuration file.
NCONF_get0_libctx() gets the library context associated with the conf parameter.
NCONF_get_section_names()
gets the names of the sections associated with
the conf as STACK_OF(OPENSSL_CSTRING) strings. The individual strings
are associated with the conf and will be invalid after conf is
freed. The returned stack must be freed with sk_OPENSSL_CSTRING_free()
.
NCONF_get_section()
gets the config values associated with the conf from
the config section name as STACK_OF(CONF_VALUE) structures. The returned
stack is associated with the conf and will be invalid after conf
is freed. It must not be freed by the caller.
NCONF_load()
returns 1 on success or 0 on error.
NCONF_new_ex()
and NCONF_new()
return a newly created CONF object
or NULL if an error occurs.
CONF_modules_load_file(3),
NCONF_new_ex()
, NCONF_get0_libctx(), and NCONF_get_section_names()
were added
in OpenSSL 3.0.
