Single tasking?

[Rick]

Hi,

Would it be right to say that C is a single-tasking environment?
pThreads and other variants aren't really "C"? Thanks

No, not really. C is a "non-tasking" environment.

pThreads and other variants aren't really "C"? Thanks

C does not support or even define the concept of "tasks", not even
single-tasking. The C language defines a virtual machine in which it
is the only thing in existence.

The C abstract machine supports a single program with a single thread
of execution (plus asynchronous invocations of signal handlers).

pThreads and other variants aren't really "C"? Thanks

You can't create a new thread in a C program without invoking undefined
behaviour. This doesn't mean that a multithreaded C program is not a C
program, merely that it is not the kind of portable C programs we discuss
in this newsgroup.
