Macros
#define	strcat(to, from) 0_DO_NOT_USE_strcat_THERE_IS_ALWAYS_A_BETTER_SOLUTION
	Force a compile time error when strcat() is used. Because the use of strcat() is a very strong indicator for poorly written code being compiled – there is always a better solution! More...

#define	strcpy(dest, source) 0_DO_NOT_USE_strcpy_DUPLICATION_IS_NOT_REQUIRED
	Force a compile time error when strcpy() is used. The use of strcpy is banned because in practice strcpy is only used by novice coders doing unnecessary duplicating. (Typically when trying to avoid using pointers when actually using pointers.) Evaluate your coding solution and avoid duplication. If you must, use the safer strncpy or snprintf. More...

Detailed Description

Standard C functions using null terminated C strings (defined in stdio.h, cstring.h)

Macro Definition Documentation

#define strcat	(	to,
		from
	)	0_DO_NOT_USE_strcat_THERE_IS_ALWAYS_A_BETTER_SOLUTION

Force a compile time error when strcat() is used.
Because the use of strcat() is a very strong indicator for poorly written code being compiled – there is always a better solution!

Unfortunately the use of #error is not possible here.

Note: Original declaration: char *strcat(char *to, const char *from); !

Definition at line 94 of file vugen.h.

#define strcpy	(	dest,
		source
	)	0_DO_NOT_USE_strcpy_DUPLICATION_IS_NOT_REQUIRED

Force a compile time error when strcpy() is used.
The use of strcpy is banned because in practice strcpy is only used by novice coders doing unnecessary duplicating. (Typically when trying to avoid using pointers when actually using pointers.)
Evaluate your coding solution and avoid duplication. If you must, use the safer strncpy or snprintf.

Note: Original declaration: char *strcpy(char *dest, const char *source); !
