When VSCode start debugging, there will be a function call before the Main function of the situation, is a very common function, according to my understanding is sure to call the Main function of the following TimerTon1 just a global function, however it is carried out, and in the case of the Main function has no call it also performs, what reason is this? Will ask god to help have a look, and it related VSCode environment configuration, configuration is as follows?

 
Unsigned char TimerTon1 (pt) Ton * 
{
Printf (" this is here \ n "); Reference 
 
 
 
 
 
 Quote: 
 
 
 
 
 
 
/* 
If (pt - & gt; BEnable==1) 
{
If (pt - & gt; BR_trig!=gTimeNumber) 
{
Pt - & gt; NET++; 
} 
Pt - & gt; NET++; 
} 

The else 
{
Pt - & gt; NET=0; 
Pt - & gt; BR_trig=0; 
} 


If (pt - & gt; NET & gt;=pt - & gt; Ntimecount) 
return 1; 
The else 
{
return 0; 
} 

Pt - & gt; BR_trig=gTimeNumber; 
*/
return 0; 
} 
Unsigned char TimerTon2 (pt) Ton * 
{
Printf (" this is here2 \ n "); 
return 0; 
} 

Void simluationtime () 
{
If (gTimeNumber==1) 
{
GTimeNumber=0; 
return; 
} 


If (gTimeNumber==0) 
{
GTimeNumber=1; 
return; 
} 
} 




Int main (int arg c, char * const argv []) 
{

Printf (" this is the main \ n "); 
/* 

T1. BEnable=1; 
T1. Ntimecount=20000; 

while(! TimerTon1 (& amp; T1)) 
{
Simluationtime (); 
} 


Printf (" timing to % d \ n ", t1.nET). 
*/
Getchar (); 
return 0;
