--- Comment #13 from Gejoe <gejoed at rediffmail dot com> ---
I modified my sample-prog.c file just by adding a line of __gcov_reset before
the while loop.
However after a.out run , the sample-prog.c.gcov file was still showing the
counters though I didn't give 'g' for __gcov_dump invocation.
Quoting a portion from sample-prog.c.gcov file :
#####: 9:int main()
-: 10:{
-: 11: unsigned char c;
-: 12: int result;
#####: 13: unsigned char data[]={127,49,255,255};
#####: 14: c = '5';
-: 15:
#####: 16: __gcov_reset();
<<<<<<<<Added here jin the original sample-prog.c file just to check the
reset behaviour
-: 17: do {
-: 18:
4: 19: c = getchar();
4: 20: result = isalnum(c);
4: 21: printf("When %c is passed, return value is %d\n", c,
result);
-: 22:
4: 23: if(c == 'g')
1: 24: __gcov_dump();
3: 25: else if(c == 'r')
#####: 26: __gcov_reset();
-: 27:
3: 28: }while(c != 'c');
I'm trying to now when would __gcov_reset help us in seeing the counter values
reset to ##### instead of old data(numbers like 4,1,3, etc in .c.gcov file).
Let me know if I miss any info.
