Manual Section... (2) - page: get_thread_area

 

NAME

get_thread_area - Get a Thread Local Storage (TLS) area  

SYNOPSIS

#include <linux/unistd.h>
#include <asm/ldt.h>

int get_thread_area(struct user_desc *u_info);  

DESCRIPTION

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_area() copies the corresponding TLS entry into the area pointed to by u_info.  

RETURN VALUE

get_thread_area() returns 0 on success. Otherwise, it returns -1 and sets errno appropriately.  

ERRORS

EFAULT
u_info is an invalid pointer.
EINVAL
u_info->entry_number is out of bounds.
 

VERSIONS

A version of get_thread_area() first appeared in Linux 2.5.32.  

CONFORMING TO

get_thread_area() is Linux-specific and should not be used in programs that are intended to be portable.  

NOTES

Glibc does not provide a wrapper for this system call; call it using syscall(2).
