PR_SET_NAME(2const) PR_SET_NAME(2const)
PR_SET_NAME, PR_GET_NAME - operations on a process or thread
Standard C library (libc, -lc)
#include <linux/prctl.h> /* Definition of PR_* constants */
#include <sys/prctl.h>
int prctl(PR_SET_NAME, char name[16]);
int prctl(PR_GET_NAME, const char name[16]);
PR_SET_NAME
Set the name of the calling thread, using the value in the
location pointed to by name.
The name can be up to 16 bytes long, including the
terminating null byte. If the length of the string,
including the terminating null byte, exceeds 16 bytes, the
string is silently truncated.
PR_GET_NAME (since Linux 2.6.11)
Return the name of the calling thread, in the buffer
pointed to by name. The returned string will be null-
terminated.
This is the same attribute that can be set via
pthread_setname_np(3) and retrieved using pthread_getname_np(3).
On success, 0 is returned. On error, -1 is returned, and errno
is set to indicate the error.
EFAULT name is an invalid address.
/proc/self/task/tid/comm
The attribute is likewise accessible via this file (see
proc_pid_comm(5)), where tid is the thread ID of the
calling thread, as returned by gettid(2).
Linux.
PR_SET_NAME
Linux 2.6.9.
