Arguments arhdr, data, elf and scn denote the data structures whose flags need to be changed. These values should have been returned by prior calls to functions in the ELF(3) API set:
Argument cmd may have the following values:
ELF_C_CLRELF_C_SETThe argument flags is allowed to have the following flags set:
ELF_F_ARCHIVEelf_flagelf()
      API. It informs the library that the application desires to create an
      ar(1) archive. Argument
      elf should have been opened for writing using the
      ELF_C_WRITE command to function
      elf_begin().ELF_F_ARCHIVE_SYSVELF_F_ARCHIVE flag to indicate that library should
      create archives that conform to System V layout rules. The default is to
      create BSD style archives.ELF_F_DIRTYELF_F_LAYOUTelf_flagelf()
      API. It informs the library that the application will take responsibility
      for the layout of the file and that the library is not to insert any
      padding in between sections.Marking a given data structure as “dirty” affects
    all of its contained elements. Thus marking an ELF descriptor
    elf with
    elf_flagelf(elf,
    ELF_C_SET, ELF_F_DIRTY) means
    that the entire contents of the descriptor are “dirty”.
Using a value of zero for argument flags will return the current set of flags for the data structure being queried.
elf_flagarhdr() function and the
  ELF_F_ARCHIVE and
  ELF_F_ARCHIVE_SYSV flags are an extension to the
  ELF(3) API.
ELF_E_ARGUMENT]ELF_E_ARGUMENT]ELF_E_ARGUMENT]ELF_E_MODE]ELF_F_ARCHIVE flag was used with an ELF
      descriptor that had not been opened for writing.ELF_E_SEQUENCE]elf_flagehdr() was called without an
      executable header being allocated.ELF_E_SEQUENCE]elf_flagphdr() was called without a
      program header being allocated.| December 3, 2011 | NetBSD 9.3 |
