| |
I was playing around with the POSIX test suite and noticed a potential problem:
- A .c file includes errno.h - errno.h #define's _ERRNO_H, does other stuff, and then includes linux/errno.h - linux/errno.h #define's _LINUX_ERRNO_H, does stuff, and then includes asm/errno.h - asm/errno.h #define's _I386_ERRNO_H (on my sys, at least) and does stuff
So far so good.
- The .c file #undef's all the EXXX errno constants. - The .c file #include's errno.h - The .c file tries to use all the EXXX constants
Problem is those *_ERRNO_H constants are still defined, so the rest of the header files don't get included.
Solutions? The easiest would be just to get rid of the #ifndef's bracketing all header files (obviously the test suite cannot be altered without breaking its validity). I'm asking for ideas on solving this problem with regards to header files in general, and the kernel includes specifically.
Suggestions are appreciated, -- Elliot Lee
