LIBRARY        top

       Standard C library (libc,-lc)

SYNOPSIS        top

#include <linux/prctl.h>/* Definition ofPR_*constants */#include <sys/prctl.h>int prctl(PR_SET_NAME, charname[16]);int prctl(PR_GET_NAME, const charname[16]);

DESCRIPTION        top

PR_SET_NAME              Set the name of the calling thread, using the value in the              location pointed to byname.              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 byname.  The returned string will be null-              terminated.       This is the same attribute that can be set viapthread_setname_np(3) and retrieved usingpthread_getname_np(3).
