QA·C Help - 0601

	0601	[E] Function 'main()' is not of type 'int (void)' or 'int (int, char *[])'.

Language extensions		REFERENCE - ISO:C90-5.1.2.2 Hosted environment

The "main" function has been defined in a non-standard form. According to the ISO:C Standard, there are only 2 acceptable ways in which the 'main' function may be defined in a hosted environment:

int main(void)
int main(int argc, char *argv[])

In the second form the function parameters may be named differently if desired.

For example:


/*PRQA S 2017 ++*/

void main(void) {                        /* Message 0601 */
    /*...*/
}

Note that in a freestanding environment the name and type of the function called at program startup are implementation-defined.
