ISC DHCP code is somewhat convoluted. Due to extensive macros use, it is often
|
||
|
|
difficult to even find whole function, much less to understand what they
|
||
|
|
actually do. One way to find such a macro-defined function is to compile the
|
||
|
|
code with debugging symbols (-g), load the binary into gdb and set a breakpoint
|
||
|
|
for such a function. gdb will print out exact place in the code where the
|
||
|
|
function is defined. Presumably one will find a macro at that specific location.
|
||
|
|
For example to find where \ref lease_reference function is defined do:
|
||
|
|
|
||
|
|
@verbatim
|
||
|
|
gdb
|
||
|
|
file dhcpd
|
||
|
|
b lease_reference
|
||
|
|
@endverbatim
