+DESCRIPTION
+ Return a pointer to the transfer vector for the object target
+ named @var{target_name}. If @var{target_name} is <<NULL>>,
+ choose the one in the environment variable <<GNUTARGET>>; if
+ that is null or not defined, then choose the first entry in the
+ target list. Passing in the string "default" or setting the
+ environment variable to "default" will cause the first entry in
+ the target list to be returned, and "target_defaulted" will be
+ set in the BFD if @var{abfd} isn't <<NULL>>. This causes
+ <<bfd_check_format>> to loop over all the targets to find the
+ one that matches the file being read.
+ If @var{is_bigendian} is not <<NULL>>, then set this value to target's
+ endian mode. True for big-endian, FALSE for little-endian or for
+ invalid target.
+ If @var{underscoring} is not <<NULL>>, then set this value to target's
+ underscoring mode. Zero for none-underscoring, -1 for invalid target,
+ else the value of target vector's symbol underscoring.
+ If @var{def_target_arch} is not <<NULL>>, then set it to the architecture
+ string specified by the target_name.
