+.SH NAME
+lc_cleanup \- Clean up internal structures after processing data.
+
+.SH SYNOPSIS
+.B #include <libconfig.h>
+.sp
+.BI "void lc_cleanup(void);"
+
+.SH DESCRIPTION
+The
+.BR lc_cleanup (3)
+function cleans up the internal structures created by calling
+.BR lc_register_var (3)
+or
+.BR lc_register_callback (3)
+and returns the memory to the application.  It is not strictly required, however memory concious programmers will still want to call this after finishing processing configuration files.
+
+After you call
+.BR lc_cleanup (3)
+calling
+.BR lc_process (3)
+or
+.BR lc_process_file (3)
+will generally cause errors since the registered variables and callbacks have been unregistered.
+
+.SH EXAMPLE
+.nf
+#include <libconfig.h>
+#include <stdlib.h>
+#include <stdio.h>
+
+int main(int argc, char **argv) {
+	int lc_p_ret, lc_rv_ret;
+	char *filename = NULL;
+
+	lc_rv_ret = lc_register_var("File", LC_VAR_STRING,
+	                            &filename, 'f');
+
+	if (lc_rv_ret != 0) {
+		fprintf(stderr, "Error registering variable: %i.\\n",
+		        lc_geterrno());
+		return(EXIT_FAILURE);
+	}
+
+	lc_p_ret = lc_process(argc, argv, "example", LC_CONF_APACHE,
+	                      NULL);
+
+	lc_cleanup();
+
+	if (lc_p_ret != 0) {
+		fprintf(stderr, "Error processing configuration: \\
+		        %s\\n", lc_geterrstr());
+		return(EXIT_FAILURE);
+	}
+
+	if (filename != NULL) {
+		printf("File specified was: %s\\n", filename);
+	} else {
+		printf("No filename specified.\\n");
