Missing ')' error while building code for STM8S105.

[ankhola]

Hi guys,

I am a newbie in STM world. I am struggling with a small code but failing every attempt modifying the code googling for several times. Please have a look to my code. I have defined three functions, i.e. inv_on(), inv_off(), and sw_state().  When these functions are called in other defined functions, two errors, i.e. missing ')' and missing ';' are showing against each called functions. But when called in main(), one error i.e. missing ')' is showing. The error messages are given as comment. Suggestion is solicited please.

Regards

When you call a function with no parameters, you don't put void.

//sw_state(void);  // invalid
sw_state();  // valid

Thanks TDK. Problem is over.
