Example
The following command invokes the TNS/R native mode C compiler and uses the NLD
directive to pass options to the nld utility:
nmc /in prog1/ prog1o;nld(-set highpin off -set highrequester off),runnable
NOEXCEPTIONS
The NOEXCEPTIONS compiler directive directs the native C++ compiler to disable
support for exceptions and exception handling.
The pragma default settings are:
Usage Guidelines
•
On Guardian, the NOEXCEPTIONS pragma can appear only on the RUN command
line for NMCPLUS or CCOMP. On OSS, the -Wnonexceptions option can
appear only on the RUN command line for the native c89 utility.
•
The NOEXCEPTIONS directive affects only native C++ programs compiled with the
VERSION2 dialect. The directive is ignored for C programs and C++ programs
compiled using VERSION1 or VERSION3.
•
The NOEXCEPTIONS directive can improve application performance by removing
unneeded processing steps with an application that does not use exceptions or
perform exception handling.
