Get the name of a keysym.
For a description of how keysyms are named, see @ref xkb_keysym_t.
@paramin keysym The keysym. @paramout buffer A string buffer to write the name into. @paramin size Size of the buffer.
@warning If the buffer passed is too small, the string is truncated (though still NUL-terminated); a size of at least 64 bytes is recommended.
@returns The number of bytes in the name, excluding the NUL byte. If the keysym is invalid, returns -1.
You may check if truncation has occurred by comparing the return value with the length of buffer, similarly to the snprintf(3) function.
