|
tep_find_function,tep_find_function_address - Find function name / start address. |
|

SYNOPSIS |
|
-------- |
|
[verse] |
|
-- |
|
*#include <event-parse.h>* |
|
|
|
const char pass:[*]*tep_find_function*(struct tep_handle pass:[*]_tep_, unsigned long long _addr_); |
|
unsigned long long *tep_find_function_address*(struct tep_handle pass:[*]_tep_, unsigned long long _addr_); |

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. |

EXAMPLE |
|
------- |

|
... |
|

|
{ |
|
const char *fname = tep_find_function(tep, addr); |
|
unsigned long long fstart = tep_find_function_address(tep, addr); |
|
|
|
/* addr is in function named fname, starting at fstart address, at offset (addr - fstart) */ |
