I have a big program to run. Using valgrind it takes hours and hours to run. I heard that there is something where we can call valgrind for a specific function in the program. And rest of program will be executed normally(without valgrind env).
Can anybody help me with this. I tried searching it over internet , May be I am missing the term to search.
It all depends on what tool you’re wanting to use. For callgrind (the profiler in valgrind) there is an option –toggle-collect=function to allow you to collect information inside a particular function and all its children.
However if the tool you’re interested in is memcheck (for capturing leaks / memory errors) then there is no available command line option.
