    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.
