Article <11605@smoke.BRL.MIL> by gwyn@brl.arpa (Doug Gwyn) says:
|[ you can use this macro to ]
|save the function-call overhead for typical strcmp() implementations:
|
|#define  StrEq( a, b )  (*(a) == *(b) && strcmp( a, b ) == 0)  /* UNSAFE */
Is it unsafe because of sideeffects of evaluating a and b twice, or is there
something else?
