Getting process status info

Is there a Win32 API call or console command
in NT that acts like the Unix "ps" command,
which gives status of all processes running
on the system? I'd prefer to execute this as
a function call from a C program.

These functions are only implemented in Windows 95. No version of NT has
them. For NT, you get this information from the registry. Take a look at
the PViewer source that comes with the Win32 SDK, or check out the "Under
the Hood" columns in the March and April '96 issues of MSJ .

Those functions will not work under Windows NT !

There is a tool called WinTop from Microsoft that shows all 32/16 bit
processes.
Look for it at www.microsoft.com

Will one or more 16-bit processes degrade system performance under Windows
95 ?
That is, will 32-bit apps run slower whenever a 16-bit app or dll is
running ?

A 16-bit process may seriously degrade performance of
threads that use user interfacve DLLs, i.e. draw or write something
on screen, manage windows, send messages, etc.
Even if these threads are 32-bit, they will be in a hung state waiting
if a badly behaved 16-bit process doesn't yield control with GetMessage()
like functions.
A 16-bit processes that behaves really well in this, e.g. spends its
life gettings messages in a loop and processing them quickly or
yielding often if it processes them for a long time, will not
seriously affect system performance.

In WIN NT you can use the Performance Monitor
app to list all running processes by selecting the
Process Object.

In Win32 API space, you can write the ps command
by using the Performance Data API's.

e-mail me if you want my "home-grown" version of ps.
