4.3.2 The Prototype for main

The prototype for the main() function is:

int main(void);

Example

The following shows an example of how main() might be defined:

int main(void)
{
 while(1)
 process();
}

Differences

The 8-bit compilers used a void return type for this function.

Migration to the CCI

Each program has one definition for the main() function. Confirm the return type for main() in all projects previously compiled for 8-bit targets.
