Seems like there should be a macro defined for that, instead. Something
like dintp() and eintp() that encapsulates them. It's unclean to have to
handcode that with asm() each time. Opens up a window for error, and makes
the code less portable.

Subject: RE: [Mspgcc-users] monitor keyword
Hello,
Be careful with using dint() eint(). If interrupts were disabled before your
function is called
you may end up enabling them. I use
asm("push r2");
dint();
....
....
asm("pop r2"); <- that assumes your function does not modify flags in the
body

Alexey
