@end table
@node Auxiliary Vector
@section Auxiliary Vector
@cindex auxiliary vector
When a program is executed, it receives information from the operating
system about the environment in which it is operating. The form of this
information is a table of key-value pairs, where the keys are from the
set of @samp{AT_} values in @file{elf.h}. Some of the data is provided
by the kernel for libc consumption, and may be obtained by ordinary
interfaces, such as @code{sysconf}. However, on a platform-by-platform
basis there may be information that is not available any other way.
@subsection Definition of @code{getauxval}
@comment sys/auxv.h
@deftypefun {unsigned long int} getauxval (unsigned long int @var{type})
This function is used to inquire about the entries in the auxiliary
vector. The @var{type} argument should be one of the @samp{AT_} symbols
defined in @file{elf.h}. If a matching entry is found, the value is
returned; if the entry is not found, zero is returned.
@end deftypefun
For some platforms, the key @code{AT_HWCAP} is the easiest way to inquire
about any instruction set extensions available at runtime. In this case,
there will (of necessity) be a platform-specific set of @samp{HWCAP_}
values masked together that describe the capabilities of the cpu on which
the program is being executed.
