I tried running the suggested command, which returns the PID of the bash shell from where the command was executed.
The thing is I need to get the PID value from the ps command instead of WINPID in a C/C++ application. Tried looking for some similar discussion in the mailing lists of Cygwin and MSYS2 and respective bug reports. But could not locate anyone having such a requirement. Otherwise, I can probably get it from the system() call using ps command and grep/awk processing it (not ideal solution).
