Hello all,
I'm currently creating a build chain where FPC is the last step, the one
producing a DLL for Windows, x86 and x64.
In front of it in the chain, I have designed a generator that creates a
program and a set of units from its own representation.
Right now, the program and units are written to disk and then FPC is
called on those files.
This works fine but is somewhat slow because of disk writing and reading.
I was thus wondering if there was a way to send the program and unit
contents directly to FPC without writing to disk, and then get FPC to
output the final DLL to a memory location as well. The last part is
optional, being able to send the program and units without disk access
would be a nice thing.
I looked around in the documentation for "standard input", "pipe", but
apart from ways to access them from within a program, I was not able to
find any information.
Is this possible? If yes, how should I proceed?
Do you have any proof that writing/reading to the files to disk is an
issue? On modern harddisks and OSes the plain I/O speed is normally not
the issue when compiling.
