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.
get_thread_area
() is Linux
specific and should not be used in programs that are intended
to be portable.
