SYNOPSIS
- asection *bfd_get_next_section_by_name (asection *sec);
+ asection *bfd_get_next_section_by_name (bfd *ibfd, asection *sec);
DESCRIPTION
Given @var{sec} is a section returned by @code{bfd_get_section_by_name},
return the next most recently created section attached to the same
- BFD with the same name. Return NULL if no such section exists.
+ BFD with the same name, or if no such section exists in the same BFD and
+ IBFD is non-NULL, the next section with the same name in any input
+ BFD following IBFD. Return NULL on finding no section.
