GET_THREAD_AREA(2) Linux Programmer's Manual GET_THREAD_AREA(2) 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. NOTES
Glibc does not provide a wrapper for this system call; call it using syscall(2). SEE ALSO
