.TH LIBCONFIG 3 "25 Oct 04" "@PACKAGE_STRING@"
.SH NAME
libconfig \- Consistent configuration library.

.SH SYNOPSIS
.B #include <libconfig.h>
.sp
.BI "int lc_register_callback(const char *" var ", char " opt ", lc_var_type_t " type ", int (*" callback ")(const char *, const char *, const char *, const char *, lc_flags_t, void *), void *" extra ");"

.BI "int lc_register_var(const char *" var ", lc_var_type_t " type ", void *" data ", char " opt ");"

.BI "int lc_process(int " argc ", char **" argv ", const char *" appname ", lc_conf_type_t " type ", const char *" extra ");"

.BI "lc_err_t lc_geterrno(void);"

.BI "char *lc_geterrstr(void);"

.BI "void lc_geterrstr(const char *" errstr ");"

.SH DESCRIPTION
Libconfig is a library to provide easy access to configuration data in a consistent and logical manner.  Variables (registered through
.BR lc_register_var (3)
or
.BR lc_register_callback (3))
are processed with the
.BR lc_process (3)
and
.BR lc_process_file (3)
functions.  Errors can be examined through
.BR lc_geterrno (3)
and
.BR lc_geterrstr (3).
Clean-up may be performed using the
.BR lc_cleanup (3)
function.

.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");
	}

	return(EXIT_SUCCESS);
}
