HI, everyone!
CCS5.3 & 6678 & WINXP
I tried to create a dll in CCS, I followed the following steps and I wonder if the file created is a dll?
1. created an empty ccs project , set the output type as "Others..." since I want a dll.(there are executable and static library).
2. created a .c file with the code :
#include <stdio.h>
__declspec(dllexport) int start();
int start()
{
printf("Hello World\n");
return 0;
}
3. I set the dynamic linking support options and changed the default output file name from .out to .dll
4. built the project and the dll was generated:
**** Build of configuration Debug for project dyna ****

Q1: Now I wonder if this file truly a DLL?
Q2: if Q1 is no. Then what is the correct way to generate a dll?
Also, I want to call the start function in other ccs project, so I :
1.added import and export symbols
2:rebult the project
3. add the dll in another ccs project " test" which is simple like:
int main(void) {
start();
return 0;
}
4. added the dynamic lib path and import symbol to the test project
4. built test

Q3: Is this the right way to call functions from in a dll?
Q4: if Q3 is no . Then how to call up a dll?
Thank you,
