SYNOPSIS
asection *bfd_get_section_by_name_if
(bfd *abfd,
const char *name,
bfd_boolean (*func) (bfd *abfd, asection *sect, void *obj),
void *obj);
DESCRIPTION
Call the provided function @var{func} for each section
attached to the BFD @var{abfd} whose name matches @var{name},
passing @var{obj} as an argument. The function will be called
