elf_flagshdr(3elf)

elf_flagdata(3ELF)           ELF Library Functions          elf_flagdata(3ELF)



NAME
       elf_flagdata,  elf_flagehdr,  elf_flagelf,  elf_flagphdr,  elf_flagscn,
       elf_flagshdr - manipulate flags

SYNOPSIS
       cc [ flag ... ] file ... -lelf [ library ... ]
       #include <libelf.h>

       uint_t elf_flagdata(Elf_Data *data, Elf_Cmd cmd, uint_t flags);


       uint_t elf_flagehdr(Elf *elf, Elf_Cmd cmd, uint_t flags);


       uint_t elf_flagelf(Elf *elf, Elf_Cmd cmd, uint_t flags);


       uint_t elf_flagphdr(Elf *elf, Elf_Cmd cmd, uint_t flags);


       uint_t elf_flagscn(Elf_Scn *scn, Elf_Cmd cmd, uint_t flags);


       uint_t elf_flagshdr(Elf_Scn *scn, Elf_Cmd cmd, uint_t flags);

DESCRIPTION
       These functions manipulate the flags associated with various structures
       of  an  ELF  file.  Given  an  ELF  descriptor (elf), a data descriptor
       (data), or a section descriptor (scn), the functions may set  or  clear
       the associated status bits, returning the updated bits. A null descrip‐
       tor is allowed, to simplify error handling; all functions return 0  for
       this degenerate case.


       cmd may have the following values:

       ELF_C_CLR    The  functions  clear the bits that are asserted in flags.
                    Only the non-zero bits in flags are cleared; zero bits  do
                    not change the status of the descriptor.


       ELF_C_SET    The  functions  set  the  bits that are asserted in flags.
                    Only the non-zero bits in flags are set; zero bits do  not
                    change the status of the descriptor.



       Descriptions of the defined flags bits appear below:

       ELF_F_DIRTY     When  the  program  intends  to write an ELF file, this
                       flag asserts the associated  information  needs  to  be
                       written  to the file. Thus, for example, a program that
                       wished to update the ELF header  of  an  existing  file
                       would  call  elf_flagehdr()  with this bit set in flags
                       and  cmd  equal  to  ELF_C_SET.   A   later   call   to
                       elf_update() would write the marked header to the file.


       ELF_F_LAYOUT    Normally,  the library decides how to arrange an output
                       file. That is, it automatically decides where to  place
                       sections,  how  to align them in the file, etc. If this
                       bit is set for an ELF descriptor, the  program  assumes
                       responsibility for determining all file positions. This
                       bit is meaningful only for elf_flagelf() and applies to
                       the entire file associated with the descriptor.



       When  a  flag  bit  is  set for an item, it affects all the subitems as
       well. Thus, for example, if the program sets the ELF_F_DIRTY  bit  with
       elf_flagelf(), the entire logical file is "dirty."

EXAMPLES
       Example 1 A sample display of calling the elf_flagdata() function.




       The  following  fragment  shows how one might mark the ELF header to be
       written to the output file:


         /* dirty ehdr ... */
         ehdr = elf32_getehdr(elf);
         elf_flagehdr(elf, ELF_C_SET, ELF_F_DIRTY);
