Subject svn commit: r564694 - /incubator/stdcxx/trunk/util/exec.cpp
Date Fri, 10 Aug 2007 17:48:02 GMT
Author: faridz

New Revision: 564694

URL: http://svn.apache.org/viewvc?view=rev&rev=564694
Log:
2007-08-10 Farid Zaripov <Farid_Zaripov@epam.com>

	* exec.cpp (fttoull) [_WIN32]: New function to convert from
	FILETIME to ULONGLONG.
	(exec_file) [_WIN32]: Get kernel time and user time of the child
	process using GetProcessTimes().
	Map STATUS_FLOAT_STACK_CHECK to SIGSTKFLT signal instead of SIGFPE.
