Profiler output: Call graph

The section "Call graph" provides for each function:

The functions that called it, the number of calls, and an estimation of the percentage of time spent in these functions.
The functions called, the number of calls, and an estimation of the time that was spent in the subroutines called from this function.

Table 1. Call graph columns
Column name	Description
index	Each function has an index which appears at the beginning of its primary line.
%total	Percentage of time spent in this function. Includes time spent in subroutines called from this function.
%self	Percentage of time spent in this function excluding the time spent in subroutines called from this function.
%child	Percentage of time spent in the functions called from this function.
calls/of	Number of calls / Total number of calls
name	Function name

Output example:

index	 %total  %self  %child  calls/of	 name

Description:

The three stars *** indicate the function that is analyzed: fb.
fc consumed 25.80% of the CPU time, 24.51% was in the called functions, 1.29% in the fc function code.
fc has been called two times (one time by main and a second time by fb)
fc has called the fa function 7 times.
fa has been called 8 times in the program.
