DESCRIPTION

naturalstrcmp is an alphanumerical comparison function that ensures x12 > x2 for example. First, the alphabetical part of the string is compared, using strcmp(3), then, if it has trailing numbers, they are compared using a numerical function.

RETURN VALUES

naturalstrcmp has the same return values than the standard library strcmp(3) function.

EXAMPLE

#include "mut.h"
static int
	connectorcmp(flc, slc)
locon_list **flc, **slc;
{
	return naturalstrcmp((*slc)->NAME, (*flc)->NAME);
}
