EMACS_SECS (TIME) is an rvalue for the seconds component of TIME.
EMACS_SET_SECS (TIME, SECONDS) sets that to SECONDS.
- EMACS_HAS_USECS is defined iff EMACS_TIME has a usecs component.
+ EMACS_HAS_USECS is defined if EMACS_TIME has a usecs component.
EMACS_USECS (TIME) is an rvalue for the microseconds component of TIME.
This returns zero if EMACS_TIME doesn't have a microseconds component.
EMACS_SET_USECS (TIME, MICROSECONDS) sets that to MICROSECONDS.
EMACS_SUB_TIME (DEST, SRC1, SRC2) subtracts SRC2 from SRC1 and
stores the result in DEST. SRC should not be negative.
- EMACS_TIME_NEG_P (TIME) is true iff TIME is negative.
+ EMACS_TIME_NEG_P (TIME) is true if TIME is negative.
