Subject: profiling question
Reply-To: djgpp AT delorie DOT com

I'm trying to to profile my program with gprof, but it always said 
that my functions ran for 0.0 ms. The sample counts is 0.05556 sec. I 
then tried rawtime() function, which  if I'm not mistaken, can track 
up to 54.945 ms. It also said that my function ran for 0 ms. So, I 
added delay(200) function at the end of my function. Now I got some 
numbers (165 ms) with rawtime(). But, the problem is gprof still 
report 0.0 ms for my function. First, I've suspected the problem was 
that because I'm calling external assembly functions, but as I tried 
with different source code in which no linking to external assembly, 
this is not the case. Furthermore, gprof doesn't report the time 
taken for calling any C library functions (there are no entries for 
that), only reports the time taken for calling my functions, which is 
all 0.0 ms. Does anybody know why this is happening ? I programmed 
under pure MS-DOS and have added -pg option when compiling.

"To know darkness, one must know the light,
To know the light, one must know darkness,
None will it be without the other,
For darkness and light is truly non-existing,
For they are all only the two sides of unity,
And all that contradicts is truly one"
