NAME

       tep_find_function, tep_find_function_address - Find function name / start address.

SYNOPSIS

       #include <event-parse.h>

       const char *tep_find_function(struct tep_handle *tep, unsigned long long addr);
       unsigned long long tep_find_function_address(struct tep_handle *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

           #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) */
           }
           ...
