NAME strxfrm - string transformation
SYNOPSIS #include <string.h> size_t strxfrm(char *dest, const char *src, size_t n);
DESCRIPTION The strxfrm() function transforms the src string into a form such that the result of str‐ cmp(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 cur‐ rent 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.
ATTRIBUTES For an explanation of the terms used in this section, see attributes(7). ┌──────────┬───────────────┬────────────────┐ │Interface │ Attribute │ Value │ ├──────────┼───────────────┼────────────────┤ │strxfrm() │ Thread safety │ MT-Safe locale │ └──────────┴───────────────┴────────────────┘
CONFORMING TO POSIX.1-2001, POSIX.1-2008, C89, C99, SVr4, 4.3BSD.
NOTES In the POSIX or C locales strxfrm() is equivalent to copying the string with strncpy(3).
