.SH SYNOPSIS
.B #include <libconfig.h>
.sp
.BI "lc_err_t lc_geterrno(void);"

.SH DESCRIPTION
The
.BR lc_geterrno (3)
function returns the last numeric error code set as an
.IR "lc_err_t"
which is an enumerated type and can be cast to any integer type.

The
.IR lc_err_t
type specifies the following defined values:
.TP
LC_ERR_NONE
No error was found.  Success.
.TP
LC_ERR_INVCMD
A command was specified for which there was no handler.
.TP
LC_ERR_INVSECTION
A section was specified for which there was no handler.
.TP
LC_ERR_INVDATA
A value that does not make sense was specified, such as a non-existant type to the
.BR lc_process_file (3)
function.
.TP
LC_ERR_BADFORMAT
An invalid format was detected, such as no argument where on was expected, or a value passed to a boolean-specified variable whose value was not one of: enable, true, yes, on, y, 1, disable, false, off, no, n, 0.
.TP
LC_ERR_CANTOPEN
Unable to open a specified file.
.TP
LC_ERR_CALLBACK
A callback function returned an error (LC_CBRET_ERROR).
.TP
LC_ERR_ENOMEM
Memory could not be allocated for internal structures.

.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);
	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);
}
