#include <stdio.h>
#include "PBI/Attribute.h"
Include dependency graph for test_attribute.c:
Defines | |
#define | YES_OR_NO "NO" |
Symbol defined to be the string YES or NO depending on wheter the attribute directive is supported. | |
#define | TEST_MISSION |
Symbol representing the string stating the mission of this test. It is purely here to make the code read nicer. | |
Functions | |
int | main (int argc, char *const argv[]) |
Standard main entry point for Unix platforms. It merely calls the testing routine test_attributes (). | |
int | test_attribute (void) |
The test program itself and also the entry point for running this test on VxWork's platforms. | |
static void | unused (void) |
As the name suggests, the unused function used to test the compiler's response to unused static functions. |

This tests whether the compiler supports the __attribute__ directive and, if not, whether PBI/Attribute.h correctly #define's it away.
It directly tests the compiler's warnings on unused static routines. If this code compiled cleanly, then the attribute feature either is supported and works correctly or the attribute feature is not supported, but the compiler does not issue warning message for unused statics.
This is currently the state of affairs with the gcc compiler and the SUN cc compiler. The gcc compiler supports this feature, so no error messages are issued. The SUN cc compiler does not support this feature, but, in turn, does not issue warning messages for unused static routines."
To run the program type
On Unix platforms: $ test_attribute On VxWorks > test_attribute ()
The program returns 0 if successful, else -1.
