Create a log file for each process in multi threaded environment

[Kubendranath]

Is it possible to write logs to different files for each process from a single point of initialization which can be further scalable dynamically if more process are added in future ..

This can be achieved by including the PID in the log file name.

If using fork() see: #3337 (comment) and #3358 (comment)

This can be achevied by creating different logger for each logger individually but i want it to be dynamic where in future if new processes get added I shouldnot be going back to the logger module to add the new line of code for the new processes,, is this possible ??

to be more specific:-

now i start my code from file1 and i write my logs of file1 in to fileA and internally in file1 i call a functoin that is in file2 now when it goes to file2 i want to write the logs of file2 to fileB and after the execution of file2 completes it returns back to file1 now again i want the logs to be written to fileA is this possible ?

So if I use extern variable that backtracking wouldnt be possible right ??

But if i initiate different loggers for each process it is possible but I want it scalable so that if I get new processes into play they need to automatically write logs to a new file instead of using the old once.

can you help me out with this ..
