Illegal macro definitions are - those not from the implementation namespace (i.e. not starting with - an underscore) or not matching any identifier mandated by The - Standard. Some common macro names are considered okay, e.g. all those - beginning with E (which may be defined in <errno.h>) or ending in - _MAX. See the arrays prefix[] and suffix[] below for details. - - In a compliant implementation no other macros can be defined, because - you could write strictly conforming programs that may fail to compile - due to syntax errors: suppose <stdio.h> defines PIPE_BUF, then the - conforming - - #include <assert.h> - #include <stdio.h> <- or where the bogus macro is defined - #include <string.h> - #define STR(x) #x - #define XSTR(x) STR(x) - int main (void) - { - int PIPE_BUF = 0; - assert (strcmp ("PIPE_BUF", XSTR (PIPE_BUF)) == 0); - return 0; - } - - is expected to compile and meet the assertion. If it does not, your - compiler compiles some other language than Standard C. - - REQUIREMENTS: - This program calls gcc to get the list of defined macros. If you - don't have gcc you're probably out of luck unless your compiler or - preprocessor has something similar to gcc's -dM option. Tune - PRINT_MACROS in this case. This program assumes headers are found - under /usr/include and that there is a writable /tmp directory. - Tune SYSTEM_INCLUDE and TMPFILE if your system differs. - #define BROKEN_SYSTEM if system(NULL) bombs -- one more violation - of ISO C, by the way. - - OUTPUT: - Each header file name is printed, followed by illegal macro names - and their definition. For the above example, you would see - ... - /usr/include/stdio.h - #define PIPE_BUF 5120 - ... - If your implementation does not yet incorporate Amendment 1 you - will see messages about iso646.h, wctype.h and wchar.h not being - found. */ - -#ifndef _GNU_SOURCE -# define _GNU_SOURCE 1 -#endif - -#include <stdio.h> -#include <stdlib.h> -#include <string.h> - -#define TMPFILE "/tmp/macros" -#define HEADER_MAX 256 - -/* ISO C header names including Amendment 1 (without ".h" suffix). */ -static char *header[] = -{ - "assert", "ctype", "errno", "float", "iso646", "limits", "locale", - "math", "setjmp", "signal", "stdarg", "stddef", "stdio", "stdlib", - "string", "time", "wchar", "wctype" -}; - -/* Macros with these prefixes are considered okay. */ -static char *prefix[] = -{ - "_", "E", "is", "str", "mem", "SIG", "FLT_", "DBL_", "LDBL_", - "LC_", "wmem", "wcs" -}; - -/* Macros with these suffixes are considered okay.
