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.
