Whoops, that should be `PROCESSENTRY32::th32ParentProcessID'.

This is not guaranteed to be possible, as there is no implicit reference that a process has on its parent.

The documented way to retrieve this information is to get a pid via CreateToolhelp32Snapshot(...TH32CS_SNAPPROCESS...) and use Process32[First|Next] until you find your process, then examining PROCESSENTRY32::th32ProcessID.

However, this is not guaranteed to work. It is quite possible that the parent process has died and the saved parent process ID has already been recycled and used by a different process (or is plain invalid). There is no way to detect this conditon, as parent-child process relationships are not `enforced' by the operating system beyond creation tine inheritance.

Hi,

how can a program find the name of the parent-process, i.e. the process it was started from?
