@xiaoxiang781216 of course - it's here and I will copy to what I think is
the offending PR.
This is is one thread:
```
typedef struct
{
pid_t pid;
uint8_t signo;
} notify_t;
static notify_t g_notify[CONFIG_MAX_NEWDATA_SIGS];
int newdata_notify(void *callback)
{
int ret;
int idx = 0;
struct sigaction act;
while ((idx < CONFIG_MAX_NEWDATA_SIGS) && g_notify[idx].pid)
{
idx++;
}
if (idx >= CONFIG_MAX_NEWDATA_SIGS)
{
ret = -EINVAL;
goto errout;
}
g_notify[idx].pid = getpid(); // <-------------------- This
returns 0 since the PR commit
g_notify[idx].signo = CONFIG_NEWDATA_SIGNO;
/* then code to set up the required sigaction and error handling */
return ret;
}
```
This is in another thread:
` ret = newdata_notify(callback_fn); `
