 |
|
hi all--
im trying to create a function to read a string and then store it in the desired variable.
i have this function:
| Code: |
char ReadStringValue[512];
void ReadString(int address,int size)
{
int offset=0;
while(offset!=size)
{
ReadStringValue[offset]=Read(address+offset,1);
offset++;
}
}
|
that will store the string into ReadStringValue, but i wanted to do that to saving the string in any array.
it should be like that:
void ReadString(int address,int size, "where to save string")
and "where to save string" should now have the string.
any help?
*note: that function is using another function i created:
Read(address,size) wich return the value (in 1,2 or 4 bits(size)) in address of a previously opened process.

http://www.cplusplus.com/doc/tutorial/pointers/
also you can probably just dumb everything down to one generic function.
"where to save string" can just be a pointer to your buffer.
also std::string would probably make your life easier and solve a lot of problems automatically
