C++ (Cpp) SYSCALL2 Examples

Example #1

File: main.c Project: nmav/cspim-ku

int main(void)
{
unsigned char string[256];
struct md5_ctx ctx;
unsigned int size;
int ret;

#ifdef REPEAT
	do {
#else
	print_string("This is the emulated program. Will try to calculate MD5...\n");
#endif


	md5_init(&ctx);

	/* pass the string address above */
#ifdef TEST
#define STR "A long text to hash, and hash, and hash and hash..."
	size = sizeof(STR)-1;
	memcpy(string, STR, size);

	md5_update(&ctx, size, string);
	md5_digest(&ctx, 16, string);

	return 0;
#else
	ret = SYSCALL2(USER_SYSCALL(1), (unsigned int)string, sizeof(string));
	if (ret > 0) {
		size = ret;
		md5_update(&ctx, size, string);
		md5_digest(&ctx, 16, string);

#ifndef REPEAT
		ret = SYSCALL2(USER_SYSCALL(2), (unsigned int)string, 16);
		if (ret == 0)
			return 0;
#endif
	}
#endif	

#ifdef REPEAT
	} while(SYSCALL1(USER_SYSCALL(0),0)==0);
#endif

	return 1;
}

Example #2

File: uname.c Project: borlox/kos

int uname(struct utsname *name)
{
	if (!name) return -1;

	int err = SYSCALL2(SC_UNAME, (uint32_t)name, L_uname);

	if (!err) {
		return 0;
	}

	return -1;
}

Example #3

File: libc.c Project: juur/FailOS

int open(const char *pathname, int flags)
{
    return (int)SYSCALL2(SYSCALL_OPEN, pathname, flags);
}

Example #4

File: getcwd.c Project: borlox/kos

char *getcwd(char *buffer, size_t count)
{
	return (char*)SYSCALL2(SC_GETCWD, (uint32_t)buffer, count);
}

Example #5

File: os.c Project: nielh/dragon

s64 ThreadCreate(thread_fnc fnc, void* param)
{
	SYSCALL2(SYS_THREADCREATE, fnc, param);
}
