| FUNCTION |
| <<strxfrm>>---transform string |
| |
| INDEX |
| strxfrm |
| |
| ANSI_SYNOPSIS |
| #include <string.h> |
| size_t strxfrm(char *restrict <[s1]>, const char *restrict <[s2]>, |
| size_t <[n]>); |
| |
| TRAD_SYNOPSIS |
| #include <string.h> |
| size_t strxfrm(<[s1]>, <[s2]>, <[n]>); |
| char *<[s1]>; |
| char *<[s2]>; |
| size_t <[n]>; |
| |
| DESCRIPTION |
| This function transforms the string pointed to by <[s2]> and |
| places the resulting string into the array pointed to by |
| <[s1]>. The transformation is such that if the <<strcmp>> |
| function is applied to the two transformed strings, it returns |
| a value greater than, equal to, or less than zero, |
| correspoinding to the result of a <<strcoll>> function applied |
| to the same two original strings. |
| |
| No more than <[n]> characters are placed into the resulting |
| array pointed to by <[s1]>, including the terminating null |
| character. If <[n]> is zero, <[s1]> may be a null pointer. If |
| copying takes place between objects that overlap, the behavior |
| is undefined. |
| |
| With a C locale, this function just copies. |
| |
| RETURNS |
| The <<strxfrm>> function returns the length of the transformed string |
| (not including the terminating null character). If the value returned |
| is <[n]> or more, the contents of the array pointed to by |
| <[s1]> are indeterminate. |
| |
| PORTABILITY |
| <<strxfrm>> is ANSI C. |
| |
| <<strxfrm>> requires no supporting OS subroutines. |
