NAME

xt_strptrcmp() - Compare two strings through char ** pointers

LIBRARY

#include <xtend/string.h>
-lxtend

SYNOPSIS

int     xt_strptrcmp(const char **p1, const char **p2)

ARGUMENTS

p1, p2: Pointers to pointers to the strings to compare

DESCRIPTION

Compare two strings via indirect pointers. This can be used by qsort(), heapsort(), etc. to sort an argv-style pointer array, swapping only the pointers rather than the string contents.

RETURN VALUES

0 if the strings are the same, a value < 0 if the string at p1 is lexically < that at p2, a value > 0 otherwise.
