You probably have an encoding issue. Did you use setlocale() to specify
the charset that your program uses? See man brlapi_writeText:
“The text is assumed to be in the current locale charset, or latin1
if locales have not been initialized. To initialize locales, use
setlocale(3).”

You mean that you don't like that the code is returned through a pointer
rather than returned? Well you can write this:
static inline brlapi_keyCode_t mybrlapi_readKey(void) {
brlapi_keyCode_t code;
if (brlapi_readKey(1, &code) <= 0)
{
fprintf(stderr,"readkey error");
exit(1);
}
return code;
}
But I doubt you actually *need* to use it as you suggested, because you
will probably rather want something like this:
switch (mybrlapi_readkey()) {
case KEY_LEFT: foo; break;
case KEY_RIGHT: foo; break;
}
which can be equally be written as:
brlapi_readkey(&code);
switch (code) {
case KEY_LEFT: foo; break;
case KEY_RIGHT: foo; break;
}
