    Command:

    get_thread_area

    
    
    

    SYNOPSIS

           #include <linux/unistd.h>
           #include <asm/ldt.h>
    
           int get_thread_area(struct user_desc *u_info);
    
           Note: There is no glibc wrapper for this system call; see NOTES.
    
    
    

    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, since it is gen-
           erally intended for use only by threading libraries.  In  the  unlikely
           event that you want to call it directly, use syscall(2).
