First and foremost, the presented information is constructed from a number of call stack samples, which represent real addresses in the application's binary code, mapped to the line numbers in the source files. This reverse mapping may not be always possible, or may be erroneous. Furthermore, due to the nature of the sampling process, it is impossible to obtain exact time measurement. Instead, time values are guesstimated by multiplying number of sample counts by mean time between two distinct samples.
The \emph{Name} column contains name of the function in which the sampling was done. Functions which were inlined are preceded with a '\faCaretRight{}' symbol. Clicking on a function will open the call stack sample parents window (see chapter~\ref{sampleparents}).
The \emph{Name} column contains name of the function in which the sampling was done. Functions which were inlined are preceded with a '\faCaretRight{}' symbol. Clicking on a function will open the call stack sample parents window (see chapter~\ref{sampleparents}). Note that if inclusive times are displayed, listed functions will be partially or completely coming from mid-stack frames, which will prevent, or limit the capability to display parent call stacks.
The \emph{Location} column displays the corresponding source file name and line number. Depending on the \emph{Location} option selection it can either show function entry address, or the instruction at which the sampling was performed. The \emph{function entry} mode points at the beginning of a non-inlined function, or at the place where inlined function was inserted in its parent function. The \emph{instruction} mode is not useful for non-inlined functions, as it points to one randomly selected sampling point out of many that were captured. However, in case of inlined functions, this random sampling point is within the inlined function body. Using these options in tandem enable you to look at both the inlined function code and the place where it was inserted. This information is complemented by the originating executable image name in the \emph{Image} column.
