Definition dllexport.h:65
Public APIs related to rb_cTime.
VALUE rb_time_nano_new(time_t sec, long nsec)
Identical to rb_time_new(), except it accepts the time in nanoseconds resolution.
Definition time.c:2746
void rb_timespec_now(struct timespec *ts)
Fills the current time into the given struct.
Definition time.c:1949
VALUE rb_time_timespec_new(const struct timespec *ts, int offset)
Creates an instance of rb_cTime, with given time and offset.
Definition time.c:2752
struct timespec rb_time_timespec(VALUE time)
Identical to rb_time_timeval(), except for return type.
Definition time.c:2915
VALUE rb_time_new(time_t sec, long usec)
Creates an instance of rb_cTime with the given time and the local timezone.
Definition time.c:2738
struct timeval rb_time_timeval(VALUE time)
Converts an instance of rb_cTime to a struct timeval that represents the identical point of time.
Definition time.c:2898
struct timeval rb_time_interval(VALUE num)
Creates a "time interval".
Definition time.c:2892
VALUE rb_time_num_new(VALUE timev, VALUE off)
Identical to rb_time_timespec_new(), except it takes Ruby values instead of C structs.
Definition time.c:2775
VALUE rb_time_utc_offset(VALUE time)
Queries the offset, in seconds between the time zone of the time and the UTC.
Definition time.c:5009
struct timespec rb_time_timespec_interval(VALUE num)
Identical to rb_time_interval(), except for return type.
Definition time.c:2929
int off
Offset inside of ptr.
Definition io.h:5
Defines RBIMPL_ATTR_NONNULL.
#define RBIMPL_ATTR_NONNULL(list)
Wraps (or simulates) __attribute__((nonnull))
