Unpacking a C struct with Pythons struct module -

i sending struct in binary format c python script.

my c struct:

struct example {     float val1;     float val2;     float val3; }

how send it:

struct example *ex; ex->val1 = 5.3f; ex->val2 = 12.5f; ex->val3 = 15.5f;  write(fd, &ex, sizeof(struct example));

how recieve:

buf = sock.recv(12) buf = struct.unpack('f f f', buf) print buf

but when print out on python side random garbage. i'm pretty sure there wrong struct definition in python i'm not sure what.

this line wrong:

write(fd, &ex, sizeof(struct example));

it should be:

write(fd, ex, sizeof(struct example));
