C++ (Cpp) trap_get_word Examples

Example #1

uaecptr consolehook_beginio(TrapContext *ctx, uaecptr request)
{
	uae_u32 io_data = trap_get_long(ctx, request + 40); // 0x28
	uae_u32 io_length = trap_get_long(ctx, request + 36); // 0x24
	uae_u32 io_actual = trap_get_long(ctx, request + 32); // 0x20
	uae_u32 io_offset = trap_get_long(ctx, request + 44); // 0x2c
	uae_u16 cmd = trap_get_word(ctx, request + 28);

	if (cmd == CMD_WRITE) {
		int len = io_length;
		char *dbuf;
		TCHAR *buf;
		if (len == -1) {
			dbuf = xmalloc(char, MAX_DPATH);
			trap_get_string(ctx, dbuf, io_data, MAX_DPATH);
			len = strlen(dbuf);
