ask for help. question about snprintf()

["Payphone LIOU" <lioupayphone@xxxxxxxxx>]

Hi, All.

 

in a kernel modules, i used "snprintf()" to ouput some strings to the terminal.

eg:

...

len = 0;

for (i = 0; i < stat->ent_count; i++) {

p = &stat->ent_stat[i];

len += snprintf((page + len), (count - len), "[%u] : id = %Lu, type = %Lu.\n", \

i, p->rs_id, p->rs_type);

}

...

 

i am sure that "stat->ent_count > 0", "count" is large enough and "page" is a valid pointer. But there is no results on the terminal.

 

so i ask for help, thx everyone.  Best Regards!
