/* The strxfrm() function transforms the src string into a form such that
|
|
* the result of strcmp() on two strings that have been transformed with
|
|
* strxfrm() is the same as the result of strcoll() on the two strings
|
|
* before their transformation. The first n characters of the transformed
|
|
* string are placed in dest.
|
|
*
|
|
* The strxfrm() function returns the number of bytes required to store
|
|
* the transformed string in dest excluding the terminating character
|
|
* If the value returned is n or more, the contents of dest are indeterminate.
|
|
*
|
|
* Note: Since this library/function only supports a single locale, no
|
|
* transformation is performed.
