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.
