Hi,
How can I close the input pipe of a process ? Suppose it keeps processing until EOF, then I have to close to handle to let it finish its job.

sysutils.fileclose(input.handle)

sysutils.fileclose(input.handle)
Won't the handle be closed again by TProcess then ? Might that not lead to closing of another opened file handle ?

It might. In fact, it probably will :)
The problem is that you cannot do a input.free, because this will not zero the stream pointer, causing an access violation when TProcess is freed...
