python - GDB command for indexing the members of a structure -

i have structure several members , see them indexed in order.

struct ant  {    int type;     char name[100];    long long int food; } 

now, when execute command in gdb

(gdb) ptype struct ant  $1 = struct  {      int type;     char name[100];    long long int food; } 

i see output like

{   0,  int type;    1,  char name[100];   2,  long long int food; } 

is there way index of each structure field in order in gdb ?

there no built-in way this. if need can write in couple of ways.

one way use gdb cli: use set logging , friends dump ptype output file, use shell run other command on file format way like.

another way use gdb's python scripting capability inspect type , display how like. if search pahole command (maybe on system, try locate pahole.py -- linux distros ship this) can see example of how done.
