[comp.unix.questions] SIGALRM signal handling and ualarm

mark@DRD.Com (Mark Lawrence) (01/12/90)

I've got a program that declares a signal handler for signals of type
SIGALRM.  I do a 
    ualarm(value,ONCE);
While in the signal handler, are further signals of type SIGALRM
blocked, i.e. if ONCE were SomeInterval, what happens when another
SIGALRM fires while I happen to be executing out of the signal handler
from a previous one?  Do I need to explicitly block them?

Oh yeah, SunOS 4.0.3 (which  may or may not be important...)
