- defined thenthe first entry in the target list is chosen.
+ 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. This causes <<bfd_check_format>> to loop over all the
targets to find the one that matches the file being read.
