Sample programs

This distribution contains sample and tutorial programs.

Library test programs

These programs also serve as library usage samples.

~/src/cpp/lib/com/Test: Tests ~/src/cpp/inc/com/. includes and ~/src/cpp/lib/com/. source library.
~/src/cpp/lib/gui/Test: Tests ~/src/cpp/inc/gui/. includes and ~/src/cpp/lib/gui/. source library.
~/src/cpp/lib/com/Test: Tests ~/src/cpp/inc/obj/. includes and ~/src/cpp/lib/obj/. source library.
~/src/cpp/lib/pub/Test: Tests ~/src/cpp/inc/pub/. includes and ~/src/cpp/lib/pub/. source library.

These are additional stress tests for the pub library. The source files are located in ~/src/cpp/Stress and object files in ~/obj/cpp/Stress/.

Common.h: Used by all stress tests
Alloc.cpp/Alloc.h: Stress tests ~/src/cpp/inc/pub/Allocator.h (This is basically a placeholder since the current Allocator.h uses malloc/free.)
Tdisp.cpp/Tdisp.h: Stress tests ~/src/cpp/inc/pub/Dispatch.h
Trace.cpp/Trace.h: Stress tests ~/src/cpp/inc/pub/Trace.h

The source files are located in ~/src/cpp/Howto/.

Getopt.cpp: Demonstrates getopt_long usage. (Now the base source file that's copy/pasted into new code.)
Macros.cpp: Demonstrates how #define statements can generally be replaced by enums because GCC optimizes out unused code.
Process.cpp: Demonstrates how to use posix_spawn and message queues, including mq_close, mq_open, mq_getattr, mq_setattr, mq_notify, mq_send, mq_receive, mq_timedreceive, and mq_unlink. The code also describes and documents message queue usage quirks that, while documented, aren't obvious.
Shared_ptr.cpp: Demonstrates how to use (and not use) std::share_ptr.
Shm_demo.cpp: Demonstrates POSIX shared memory usage, with and without an associated memory mapped file.
Verify.cpp: Doesn't demonstrate anything. It just verifies expected operation sequences.
