strxfrm(3)

NAME

     strxfrm -- 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.

SEE ALSO

     setlocale(3), strcmp(3), strcoll(3), wcsxfrm(3)

STANDARDS

     The strxfrm() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
