7

SYNOPSIS

9       #include <stringprep.h>
10
11       uint32_t  *  stringprep_utf8_to_ucs4(const  char  *  str,  ssize_t len,
12       size_t * items_written);
13

ARGUMENTS

15       const char * str
16                   a UTF-8 encoded string
17
18       ssize_t len the maximum length of  str to use. If  len <  0,  then  the
19                   string is nul-terminated.
20
21       size_t * items_written
22                   location  to  store the number of characters in the result,
23                   or NULL.
24

DESCRIPTION

26       Convert a string from UTF-8 to a 32-bit fixed width  representation  as
27       UCS-4.  The function now performs error checking to verify that the in‐
28       put is valid UTF-8 (before it was documented to not do error checking).
29
30       Return value: a pointer to a newly allocated UCS-4 string.  This  value
31       must be deallocated by the caller.
