| NAME |
| ---- |
| 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 |
| ------- |
| [source,c] |
| -- |
| #include <event-parse.h> |
| ... |
| struct tep_handle *tep = tep_alloc(); |
| ... |
| void show_function( unsigned long long addr) |
| { |
| 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) */ |
| } |
| ... |
