\"handy.h\"

[Larry Wall]

Here's a chunk of code straight out of rn:

/* some handy defs */

#define bool char
#define TRUE (1)
#define FALSE (0)
#define Null(t) ((t)0)
#define Nullch Null(char *)
#define Nullfp Null(FILE *)

#define Ctl(ch) (ch & 037)

#define strNE(s1,s2) (strcmp(s1,s2))
#define strEQ(s1,s2) (!strcmp(s1,s2))
#define strnNE(s1,s2,l) (strncmp(s1,s2,l))
#define strnEQ(s1,s2,l) (!strncmp(s1,s2,l))
