DESCRIPTION
|
||
|
|
-----------
|
||
|
|
These functions can be used to find function name and start address, by given
|
||
|
|
address. The given address does not have to be exact, it will select the function
|
||
|
|
that would contain it.
|
||
|
|
|
||
|
|
The _tep_find_function()_ function returns the function name, which contains the
|
||
|
|
given address _addr_. The _tep_ argument is the trace event parser context.
|
||
|
|
|
||
|
|
The _tep_find_function_address()_ function returns the function start address,
|
||
|
|
by given address _addr_. The _addr_ does not have to be exact, it will select the
|
||
|
|
function that would contain it. The _tep_ argument is the trace event parser context.
|
||
|
|
|
||
|
|
RETURN VALUE
|
||
|
|
------------
|
||
|
|
The _tep_find_function()_ function returns the function name, or NULL in case
|
||
|
|
it cannot be found.
|
||
|
|
|
||
|
|
The _tep_find_function_address()_ function returns the function start address,
|
||
|
|
or 0 in case it cannot be found.
