signal (ULTRIX) signal (ULTRIX)
NAME
signal - Modifies signal functions
BSD COMPATIBILITY
The Digital UNIX system provides the libbsd.a library to allow you to
use library functions that are compatible with ULTRIX BSD library func‐
tions. To use the BSD functions, your program needs to be compiled with
-D_BSD and the -lbsd options.
Causes the system to preserve the value of the SA_RESTART flag if your
process explicitly enables or disables system call restart by using the
siginterrupt() call.
SYSTEM V COMPATIBILITY
Digital UNIX provides the libsys5.a library to allow you to use library
functions that are compatible with System V library functions. This
library contains functions for those libc functions whose behavior is
incompatible with POSIX or X/Open standards. The ULTRIX system also
provides a System V compatibility library, libcV.a, which supplies a
number of features similar to those that libsys5.a provides. The most
significant behavior of the functions in this library is the compati‐
bility with System V nonblocked signals. For more information about
the System V (SVID-2) features in Digital UNIX, please refer to the
System V Compatibility User's Guide.
The specified signal is not blocked from delivery when the handler is
entered, and the disposition of the signal reverts to SIG_DFL when the
signal is delivered.
