TODO revision 23658aa159730be559201e7e25fdade5853efa0e 
1* {enable,disable}_all_breakpoints should be process-dependent
2
3* All wait4's should be moved to chld_handler():
4  + A process may stop because:
5    - It execve()'d (needs breakpoints to be added)
6    - It received a signal                          (DONE)
7    - It breakpointed at a library call             (DONE)
8    - It breakpointed at a library return
9    - It breakpointed at a syscall
10    - It breakpointed at a syscall return
11
12* ``struct_process'' should also have:
13  + The state of the process:
14    - uninitialized               (DONE)
15    - running
16    - within a given library call
17    - within a given syscall      (DONE)
18  + All the symbols it has breakpointed, and, for each of them:
19    - its addr
20    - its return addr, if any
21    - whether the return addr is breakpointed (ie, if the symbol is ``active'')
22    - the original value in the addr, and in the return addr, if appropiate
23
24* I should parse a config file (/etc/ltrace.conf & ~/.ltracerc) to
25  handle different arguments to the library calls
26
27* ltrace should accept `-p' option. (hey, it's not as difficult as it
28  seems)
29
30* return values should be logged.  That implies:
31  + Breakpointing each return value
32  + Disabling breakpoints and displaying ``???'' as return value when
33    a new function is called
34
35* All architecture dependent stuff should be moved to ``arch.h''
