uconvert(3) Allegro manual uconvert(3)NAMEuconvert - High level string encoding conversion wrapper. Allegro game
programming library.
SYNOPSIS
#include <allegro.h>
char *uconvert(const char *s, int type, char *buf, int newtype, int
size);
DESCRIPTION
Higher level function running on top of do_uconvert(). This function
converts the specified string `s' from `type' to `newtype', storing at
most `size' bytes into the output `buf' (including the terminating null
character), but it checks before doing the conversion, and doesn't
bother if the string formats are already the same (either both types
are equal, or one is ASCII, the other is UTF-8, and the string contains
only 7-bit ASCII characters).
As a convenience, if `buf' is NULL it will convert the string into an
internal static buffer and the `size' parameter will be ignored. You
should be wary of using this feature, though, because that buffer will
be overwritten the next time this routine is called, so don't expect
the data to persist across any other library calls. The static buffer
may hold less than 1024 characters, so you won't be able to convert
large chunks of text. Example:
char *p = uconvert(input_string, U_CURRENT, buffer, U_ASCII, 256);
RETURN VALUE
Returns a pointer to `buf' (or the static buffer if you used NULL) if a
conversion was performed. Otherwise returns a copy of `s'. In any
cases, you should use the return value rather than assuming that the
string will always be moved to `buf'.
