NAME
getthreadarea - get a thread-local storage (TLS) area SYNOPSIS
#include
#include
int getthreadarea(struct userdesc *uinfo); Note: There is no glibc wrapper for this system call; see NOTES. DESCRIPTION getthreadarea() returns an entry in the current thread's thread-local storage (TLS) array. The index of the entry corresponds to the value
of uinfo->entrynumber, passed in by the user. If the value is in bounds, getthreadarea() copies the corresponding TLS entry into the area pointed to by uinfo. RETURN VALUE
getthreadarea() returns 0 on success. Otherwise, it returns -1 and sets errno appropriately. ERRORS EFAULT uinfo is an invalid pointer.
EINVAL uinfo->entrynumber is out of bounds. VERSIONS A version of getthreadarea() first appeared in Linux 2.5.32. CONFORMING TO
getthreadarea() 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, since it is gen‐ erally intended for use only by threading libraries. In the unlikely event that you want to call it directly, use syscall(2). SEE ALSO modifyldt(2), setthreadarea(2) COLOPHON
