get_thread_area - Get a Thread Local Storage (TLS) area
int get_thread_area(struct user_desc *u_info);
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.
get_thread_area() returns 0 on success. Otherwise, it returns -1 and
sets errno appropriately.
EFAULT u_info is an invalid pointer.
EINVAL u_info->entry_number is out of bounds.
A version of get_thread_area() first appeared in Linux 2.5.32.
get_thread_area() is Linux-specific and should not be used in programs
that are intended to be portable.
Glibc does not provide a wrapper for this system call; call it using
