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_CLR
ELF_C_SET
The argument flags is allowed to have the following flags set:
ELF_F_ARCHIVE
elf_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_SYSV
ELF_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_DIRTY
ELF_F_LAYOUT
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.
elf_flagarhdr
() function and the
ELF_F_ARCHIVE
and
ELF_F_ARCHIVE_SYSV
flags are an extension to the
ELF(3) API.
