From d7d785916619f752ecf7e67e82055fb1cb9216ba Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Tue, 11 Mar 2008 20:07:49 +0000 Subject: 2008-03-11 Joel Sherrill * rtems/Makefile.am, rtems/include/rtems/rtems/clock.h, rtems/src/clockget.c: * rtems/src/clockgetsecondssinceepoch.c, rtems/src/clockgettickspersecond.c, rtems/src/clockgettickssinceboot.c, rtems/src/clockgettod.c, rtems/src/clockgettodtimeval.c: New files. Refactored rtems_clock_get into 5 methods which are single purpose and more strongly typed. They are: rtems_clock_get_tod - Get TOD in Classic API structure rtems_clock_get_tod_timeval - Get TOD in struct timeval rtems_clock_get_seconds_since_epoch - Get TOD as seconds since 1988 rtems_clock_get_ticks_since_boot - Get ticks since boot rtems_clock_get_ticks_per_second - Get ticks per second --- cpukit/rtems/src/clockgettod.c | 56 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 cpukit/rtems/src/clockgettod.c (limited to 'cpukit/rtems/src/clockgettod.c') diff --git a/cpukit/rtems/src/clockgettod.c b/cpukit/rtems/src/clockgettod.c new file mode 100644 index 0000000000..9347d797ee --- /dev/null +++ b/cpukit/rtems/src/clockgettod.c @@ -0,0 +1,56 @@ +/* + * Clock Manager - rtems_clock_get_tod + * + * COPYRIGHT (c) 1989-2007. + * On-Line Applications Research Corporation (OAR). + * + * The license and distribution terms for this file may be + * found in the file LICENSE in this distribution or at + * http://www.rtems.com/license/LICENSE. + * + * $Id$ + */ + +#if HAVE_CONFIG_H +#include "config.h" +#endif + +#include +#include +#include +#include +#include +#include +#include + +rtems_status_code rtems_clock_get_tod( + rtems_time_of_day *time_buffer +) +{ + rtems_time_of_day *tmbuf = time_buffer; + struct tm time; + struct timeval now; + + if ( !time_buffer ) + return RTEMS_INVALID_ADDRESS; + + if ( !_TOD_Is_set ) + return RTEMS_NOT_DEFINED; + + /* Obtain the current time */ + _TOD_Get_timeval( &now ); + + /* Split it into a closer format */ + gmtime_r( &now.tv_sec, &time ); + + /* Now adjust it to the RTEMS format */ + tmbuf->year = time.tm_year + 1900; + tmbuf->month = time.tm_mon + 1; + tmbuf->day = time.tm_mday; + tmbuf->hour = time.tm_hour; + tmbuf->minute = time.tm_min; + tmbuf->second = time.tm_sec; + tmbuf->ticks = now.tv_usec / _TOD_Microseconds_per_tick; + + return RTEMS_SUCCESSFUL; +} -- cgit v1.2.3
