Define Documentation

#define resched_init (  timer, type, sec, usec   )

For internal use only. This macro initializes an element of the test timer reschedule array. Warning: This macro evaluates the type argument multiple times. Parameters: [in]  timer  The index of the timer to reschedule. [in]  type  One of TT_ABSOLUTE, TT_RELATIVE, or TT_PERIODIC, to specify the desired timer type. [in]  sec  The seconds value for the timer expiration time. [in]  usec  The microseconds value for the timer expiration time. Definition at line 207 of file t_timer_fcns.c.

#define timer_init (  type, sec, usec, flags   )

For internal use only. This macro initializes an element of the test timer array. Warning: This macro evaluates the type argument multiple times. Parameters: [in]  type  One of TT_ABSOLUTE, TT_RELATIVE, or TT_PERIODIC, to specify the desired timer type. [in]  sec  The seconds value for the timer expiration time. [in]  usec  The microseconds value for the timer expiration time. [in]  flags  Flags affecting how the timer will be tested. Definition at line 122 of file t_timer_fcns.c.

#define TT_FLAG_DESTROY

For internal use only. This flag indicates that the timer will be passed to timer_destroy() in order to test that function. Definition at line 103 of file t_timer_fcns.c. Referenced by main().

#define TTF_SEC

For internal use only. This macro simply contains the number of seconds for the "current" time for testing purposes. (There's nothing special about this number; it's just the value for Monday, September 12, 21:03:15 EDT 2005, which just happens to be when this test program was written.) Definition at line 47 of file t_timer_fcns.c. Referenced by gettimeofday().

#define TTF_USEC

For internal use only. This macro simply contains the number of microseconds for the "current" time for testing purposes. (There's nothing special about this number; see TTF_SEC.) Definition at line 56 of file t_timer_fcns.c. Referenced by gettimeofday().

Function Documentation

int gettimeofday (  struct timeval *  tv, struct timezone *  tz )

For internal use only. This is an override of the C library's gettimeofday() function. Since it's not ANSI, we're supposed to be able to do so. We're doing this to be able to control what periodic and relative timers have their expire time set to, for testing purposes. Parameters: [in]  tv  A struct timeval to be filled in. [in]  tz  The timezone (obsolete). Return values: 0  The operation completed successfully. -1  There was an error getting the time. Definition at line 73 of file t_timer_fcns.c. References TTF_SEC, and TTF_USEC.

int main (  int  argc, char **  argv )

For internal use only. This program is used for testing the timer manipulation functions timer_create(), timer_destroy(), and timer_resched(). Definition at line 357 of file t_timer_fcns.c. References ev_lib_init, ev_prog_name, ev_test_init, prog, ti_expire, ti_type, ti_value, timer_create(), timer_destroy(), timer_resched(), and TT_FLAG_DESTROY.
