|
* arg2 (int), using the value in the location pointed to by required arg1
|
|
* (char*). The name can be up to CONFIG_TASK_NAME_SIZE long (including
|
|
* any null termination). The thread ID of 0 will set the name of the

|
* PR_GET_NAME
|
|

* termination). As an example:
|
|
*
|
|
* char myname[CONFIG_TASK_NAME_SIZE];
|
|
* prctl(PR_GET_NAME, myname, 0);
