            Bug ID: 218018
           Summary: dl_iterate_phdr should mention Elf64_Phdr (in addition
                    to Elf32_Phdr).
           Product: Documentation
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: man-pages
          Assignee: documentation_man-pages@kernel-bugs.osdl.org
          Reporter: ppluzhnikov@google.com
        Regression: No

dl_iterate_phdr should mention Elf64_Phdr (in addition to Elf32_Phdr).
Currently the man page says:

These program headers are structures of the following form:
  typedef { ... } Elf32_Phdr;

which is obviously wrong for 64-bit binaries.

Hello Paul,

Do you think the following would be helpful.

Replacing "These program headers are structures of the following form:" with
the following

The ELF program header is described by the type Elf32_Phdr or Elf64_Phdr
depending on the architecture. Following is an example of 32 bit architecture.
Refer to elf (man elf) for more information on 64 bit architecture.

Sure.

I suggest deleting the last 4 words, i.e.

  Refer to elf (man elf) for more information.

since "man elf" describes both Elf{32,64}_Phdr in a bit more detail.

I suggest creating link pages Elf32_Phdr(3type) and Elf64_Phdr(3type)
both of which link to elf(5).
