hi all, which one of the following is better performance wise. #define WHITESPACES " \t\r\n" char* eat_whites(char *p) { while(*p && strchr(WHITESPACES,*p)) { p++; }/* while(*p && strchr(WHITESPACES,*p)) */ return p; }/* eat_whites() */ char* eat_whites(char *p) { while(*p && isspace(*p)) { p++; }/* while(*p && isspace(*p)) */ return p; }/* eat_whites() */
