get_thread_area − Get a Thread Local Storage (TLS) area
#include
<linux/unistd.h>
#include <asm/ldt.h>
int get_thread_area(struct user_desc *u_info);
get_thread_area() returns an entry in the current thread’s Thread Local Storage (TLS) array. The index of the entry corresponds to the value of u_info->entry_number, passed in by the user. If the value is in bounds, get_thread_info copies the corresponding TLS entry into the area pointed to by u_info.
get_thread_area() returns 0 on success. Otherwise, it returns −1 and sets errno appropriately.
EFAULT |
u_info is an invalid pointer. |

EINVAL |
u_info->entry_number is out of bounds. |
get_thread_area() is Linux specific and should not be used in programs that are intended to be portable.
A version of get_thread_area() first appeared in Linux 2.5.32.
