xt_strptrcmp(3)

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.
