Doubt on function routine

i have a function

Code:

---

void SendData(sint32_t data)
{
  Transmit();
}

---

One problem i am seeing is i need to send data of max size of uint32_t and also a function requiring to transmit a data of sint32_t also. If i use the uint32_t to SendData it will exceed the size. How do I do, do i need to write separate function for each data type?

Maybe review your other threads on the same subject:
MSB and LSB of the signed value
Signed and Unsigned Variables
Missing basics of signed and unsigned numbers (this was 3 years ago)

Mostly, the data transmission functions like read()/write() or recv()/send() don't give a damn about sign or endianess.

Code:

---

void SendData(void *data, size_t size)
{
  Transmit();
}

---

In your other code, you do

Code:

---

sint32_t a;
uint32_t b;
SendData(&a, sizeof(a));
SendData(&b, sizeof(b));

---

To SendData(), it's just a simple block of memory of a given size.
It neither needs to know, or cares to know what it actually represents.
