Name
get_thread_area — Get a Thread Local Storage (TLS)
area
Synopsis
int
get_thread_area( |
struct user_desc

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

specific and should not be used in programs that are intended
to be portable.
