NAME

uaddr - User space address of current running task. EXPERIMENTAL.

SYNOPSIS

    uaddr:long()

ARGUMENTS

None

DESCRIPTION

Returns the address in userspace that the current task was at when the probe occurred. When the current running task isn't a user space thread, or the address cannot be found, zero is returned. Can be used to see where the current task is combined with usymname or symdata. Often the task will be in the VDSO where it entered the kernel. FIXME - need VDSO tracking support #10080.
