do_uconvert(3alleg4)                                              Allegro manual                                              do_uconvert(3alleg4)

NAME

       do_uconvert - Converts a string to another encoding format. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       void do_uconvert(const char *s, int type, char *buf, int newtype, int size);

DESCRIPTION

       Converts the specified string `s' from `type' to `newtype', storing at most `size' bytes into the output `buf'. The type parameters can use
       the value U_CURRENT as a shortcut to represent the currently selected encoding format. Example:

          char temp_string[256];
          do_uconvert(input_string, U_CURRENT, temp_string, U_ASCII, 256);

       Note that, even for empty strings, your destination string must have at least enough bytes to store the terminating null character  of  the
       string,  and  your  parameter `size' must reflect this. Otherwise, the debug version of Allegro will abort at an assertion, and the release
       version of Allegro will overrun the destination buffer.

NAME

       uconvert - 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 con-
       tains 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'.
