srn_namespace_load()

srn_namespace_t * srn_namespace_load

(

srn_namespace_t *

ns

)

Load the namespace's source from the filesystem into src_buffer, parse it, and populate the symbol table.

Not implemented, the current body returns null unconditionally, so callers cannot rely on it yet.

srn_namespace_make()

srn_value_t * srn_namespace_make	(	srn_context_t *	ctx,
		srn_metadata_t *	metadata,
		srn_string_t *	name )

Creates a new namespace in the give context.

The given context will NOT be the namespace's root context
