Parallel Port with C/C++

Parallel Port with C/C++

Parallel Port with C/C++

(OP)
How can I read/write bits in the parallel port usin C/C++ in WinXP? Because direct hardware access in 32-bit Windows is generally not allowed. While it can be done in the Win9x OS by using inline assembly, this is generally discouraged as this technique is not supported under WinNT.

And the following program features and language elements are either no longer supported or no longer used in C++Builder 5.5:

inport
inportb
outport
