STRXFRM(3) BSD Library Functions Manual STRXFRM(3)NAMEstrxfrm — transform a string under locale
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <string.h>
size_t
strxfrm(char * restrict dst, const char * restrict src, size_t n);
DESCRIPTION
The strxfrm() function transforms a null-terminated string pointed to by
src according to the current locale collation if any, then copies the
transformed string into dst. Not more than n characters are copied into
dst, including the terminating null character added. If n is set to 0
(it helps to determine an actual size needed for transformation), dst is
permitted to be a NULL pointer.
Comparing two strings using strcmp() after strxfrm() is equal to compar‐
ing two original strings with strcoll().
RETURN VALUES
Upon successful completion, strxfrm() returns the length of the trans‐
formed string not including the terminating null character. If this
value is n or more, the contents of dst are indeterminate.
