FUNCTION::SPRINT_BAC(3stap) Context Functions FUNCTION::SPRINT_BAC(3stap)NAME
function::sprint_backtrace - Return stack back trace as string
Returns a simple (kernel) backtrace. One line per address. Includes the symbol name (or hex address if symbol couldn't be resolved) and
module name (if found). Includes the offset from the start of the function if found, otherwise the offset will be added to the module (if
found, between brackets). Returns the backtrace as string (each line terminated by a newline character). Note that the returned stack will
be truncated to MAXSTRINGLEN, to print fuller and richer stacks use print_backtrace. Equivalent to sprint_stack(backtrace), but more
efficient (no need to translate between hex strings and final backtrace string).

FUNCTION:(3stap) Time utility functions FUNCTION:(3stap)NAME
function::ctime - Convert seconds since epoch into human readable date/time string
Number of seconds since epoch (as returned by gettimeofday_s)
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) the returned string will be "a long, long time ago...". If the time would be unreasonable far in
the future the returned string will be "far far in the future..." (both these strings are also 24 characters wide).
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.
