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 threads 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
u_info is an invalid pointer.
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.
