strxfrm - Man Page

string transformation

Library

Standard C library (libc, -lc)

Synopsis

#include <string.h>

size_t strxfrm(char *restrict dest, const char *restrict src,
               size_t n);

Description

The strxfrm() function transforms the src string into a form such that the result of strcmp(3) on two strings that have been transformed with strxfrm() is the same as the result of strcoll(3) on the two strings before their transformation. The first n bytes of the transformed string are placed in dest. The transformation is based on the program's current locale for category LC_COLLATE. (See setlocale(3)).

Return Value

The strxfrm() function returns the number of bytes required to store the transformed string in dest excluding the terminating null byte ('\0'). If the value returned is n or more, the contents of dest are indeterminate.
