GET_THREAD_AREA(2)	   Linux Programmers Manual	   GET_THREAD_AREA(2)



NAME
       get_thread_area - Get a Thread Local Storage (TLS) area

SYNOPSIS
       #include 
       #include 

       int get_thread_area(struct user_desc *u_info);

DESCRIPTION
       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_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.
