FUNCTION::SET_KERNEL(3stap)				  String and data writing functi			       FUNCTION::SET_KERNEL(3stap)

NAME

       function::set_kernel_string - Writes a string to kernel memory

SYNOPSIS

	   set_kernel_string(addr:long,val:string)

ARGUMENTS

       addr
	   The kernel address to write the string to

       val
	   The string which is to be written

DESCRIPTION

       Writes the given string to a given kernel memory address. Reports an error on string copy fault. Requires the use of guru mode (-g).

NAME

       function::ctime - Convert seconds since epoch into human readable date/time string

SYNOPSIS

	   ctime:string(epochsecs:long)

ARGUMENTS

       epochsecs
	   Number of seconds since epoch (as returned by gettimeofday_s)

DESCRIPTION

       Takes an argument of seconds since the epoch as returned by gettimeofday_s. Returns a string of the form

       "Wed Jun 30 21:49:08 1993"

       The string will always be exactly 24 characters. If the time would be unreasonable far in the past (before what can be represented with a
       32 bit offset in seconds from the epoch) an error will occur (which can be avoided with try/catch). If the time would be unreasonable far
       in the future, an error will also occur.

       Note that the epoch (zero) corresponds to

       "Thu Jan 1 00:00:00 1970"

       The earliest full date given by ctime, corresponding to epochsecs -2147483648 is "Fri Dec 13 20:45:52 1901". The latest full date given by
       ctime, corresponding to epochsecs 2147483647 is "Tue Jan 19 03:14:07 2038".

       The abbreviations for the days of the week are 'Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', and 'Sat'. The abbreviations for the months are
       'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', and 'Dec'.

       Note that the real C library ctime function puts a newline ('
') character at the end of the string that this function does not. Also note
       that since the kernel has no concept of timezones, the returned time is always in GMT.
