ELF_FLAGDATA(3) 		   BSD Library Functions Manual 		  ELF_FLAGDATA(3)

NAME
     elf_flagdata, elf_flagehdr, elf_flagelf, elf_flagphdr, elf_flagscn, elf_flagshdr -- manipu-
     late flags associated with ELF(3) data structures

LIBRARY
     library ``libelf''

SYNOPSIS
     #include <libelf.h>

     unsigned int
     elf_flagdata(Elf_Data *data, Elf_Cmd cmd, unsigned int flags);

     unsigned int
     elf_flagehdr(Elf *elf, Elf_Cmd cmd, unsigned int flags);

     unsigned int
     elf_flagelf(Elf *elf, Elf_Cmd cmd, unsigned int flags);

     unsigned int
     elf_flagphdr(Elf *elf, Elf_Cmd cmd, unsigned int flags);

     unsigned int
     elf_flagscn(Elf_Scn *scn, Elf_Cmd cmd, unsigned int flags);

     unsigned int
     elf_flagshdr(Elf_Scn *scn, Elf_Cmd cmd, unsigned int flags);

DESCRIPTION
     These functions are used to query, set or reset flags on data structures associated with an
     ELF file.

     Arguments data, elf and scn denote the data structures whose flags need to be changed.
     These values are allowed to be NULL to simplify error handling in application code.

     Argument cmd may have the following values:

     ELF_C_CLR	The argument flags specifies the flags to be cleared.

     ELF_C_SET	The argument flags specifies the flags to be set.

     The argument flags is allowed to have the following flags set:

     ELF_F_DIRTY   Mark the associated data structure as needing to be written back to the under-
		   lying file.	A subsequent call to elf_update(3) will resynchronize the
		   library's internal data structures.

     ELF_F_LAYOUT  This flag is only valid with the elf_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.

RETURN VALUES
     These functions return the updated flags is successful, and zero if an error is detected.

ERRORS
     These functions may fail with the following errors:

     [ELF_E_ARGUMENT]  An unsupported value was used for the cmd argument.

     [ELF_E_ARGUMENT]  Argument flags had unsupported flags set.

     [ELF_E_ARGUMENT]  The argument elf was not a descriptor for an ELF object.

     [ELF_E_SEQUENCE]  Function elf_flagehdr() was called without an executable header being
		       allocated.

     [ELF_E_SEQUENCE]  Function elf_flagphdr() was called without a program header being allo-
		       cated.
