Dear All.
Currently to implement logger we use the following approach (the code was
implemented for Delphi/Kylix/FPC).
Logger is intended for displaying in the GUI outputs of several threads and
child processes and also for storage into internal bases.
Logic is the following:
Get stdout handle (duplicate it under linux),
create pipe,
replace the stdout (keeping the old stdout) for current process with write
handle of pipe,
There are following problems with FPC
Under Windows: I have to call rewrite(output) for every thread which wants to
use new (captured) stdout
So the questions:
How to force all the threads of process and all DLLs write into same captured
stdout?
There is no way that I know of to avoid the rewrite(), since the file descriptor
records for Input, Output and StdErr are threadvars.
And the threadvars must be initialized on thread start.
How to revert stdout back (stop capturing)?
Close and reopen using the standard filedescriptors ?
