NAME

       stringprep_utf8_to_ucs4 - API function

SYNOPSIS

       #include <stringprep.h>

       uint32_t * stringprep_utf8_to_ucs4(const char * str, ssize_t len, size_t * items_written);

ARGUMENTS

       const char * str
                   a UTF-8 encoded string

       ssize_t len the  maximum  length  of   str  to  use.  If   len  <  0,  then  the string is
                   nul-terminated.

       size_t * items_written
                   location to store the number of characters in the result, or NULL.

DESCRIPTION

       Convert a string from UTF-8 to a 32-bit fixed width representation as UCS-4.  The function
       now  performs  error  checking  to  verify  that  the  input is valid UTF-8 (before it was
       documented to not do error checking).

       Return value: a pointer to a newly allocated UCS-4 string.  This value must be deallocated
       by the caller.
