Re: [PHP-DEV] return values of socket_recvmsg
The return data in PHP is "$data" which is an array with 4 elements,
does it match to "zmsg" inside of c function
"socket_recvmsg"(/home/work/php/php/ext/sockets/sendrecvmsg.c:214)?
Here zmsg is struct with:
(gdb) ptype zmsg
type = struct _zval_struct {
zend_value value;
union {
struct {...} v;
uint32_t type_info;
} u1;
union {
uint32_t next;
uint32_t cache_slot;
uint32_t lineno;
uint32_t num_args;
uint32_t fe_pos;
uint32_t fe_iter_idx;
uint32_t access_flags;
uint32_t property_guard;
uint32_t extra;
} u2;
} *
How do these two variables match between php and C?
Thanks,
Sam

Re: [PHP-DEV] return values of socket_recvmsg
Thank Kalle, I knew the implementaion of socket_recvmsg(), but want to know the return data structure. The test on Big_endian (s390x) got a little different return result than on x86_64, try to dig out where the problem is.

[PHP-DEV] return values of socket_recvmsg
The test case ext/sockets/tests/socket_recvmsg.php has following output
on x86_64:
===
...
1 Array
2 (
3[name] => Array
4(
5[family] => 10
6[addr] => ::1
7[port] => 7001
8[flowinfo] => 0
9[scope_id] => 0
10)
11
12[control] => Array
13 (
14[0] => Array
15 (
16[level] => 41
17[type] => 50
18[data] => Array
19 (
20[addr] => ::1
21[ifindex] => 1
22)
23)
24)
...
===
This is output by c
function:"socket_recvmsg"(/home/work/php/php/ext/sockets/sendrecvmsg.c:214),
which returns a struct "executor_globals.current_execute_data".
The struct is defined as :
(gdb) ptype executor_globals.current_execute_data
type = struct _zend_execute_data {
const zend_op *opline;
zend_execute_data *call;
zval *return_value;
zend_function *func;
zval This;
zend_execute_data *prev_execute_data;
zend_array *symbol_table;
void **run_time_cache;
zval *literals;
} *
Where do the above output values (line 18-21) store in the struct
_zend_execute_data ?
Thanks,
Sam
