Return true (nonzero) if the standard I/O file fp with name
filename is deemed interactive. This is the case for files
for which "isatty(fileno(fp))" is true. If the global
flag Py_InteractiveFlag is true, this function also returns
true if the filename pointer is NULL or if the name is
equal to one of the strings '<stdin>' or '???'.
Return the time of last modification of the file filename.
The result is encoded in the same way as the timestamp returned by
the standard C library function time().
Function to update some internal state after a process fork; this
should be called in the new process if the Python interpreter will
continue to be used. If a new executable is loaded into the new
process, this function does not need to be called.
Return true when the interpreter runs out of stack space. This is a
reliable check, but is only available when USE_STACKCHECK
is defined (currently on Windows using the Microsoft Visual C++
compiler and on the Macintosh). USE_CHECKSTACK will be
defined automatically; you should never change the definition in
your own code.
Return the current signal handler for signal i. This is a
thin wrapper around either sigaction() or
signal(). Do not call those functions directly!
PyOS_sighandler_t is a typedef alias for void
(*)(int).
Set the signal handler for signal i to be h; return the
old signal handler. This is a thin wrapper around either
sigaction() or signal(). Do not call those
functions directly! PyOS_sighandler_t is a typedef alias
for void (*)(int).
