Elf32_Shdr *elf32_getshdr(Elf_Scn *scn);
Elf64_Shdr *elf64_getshdr(Elf_Scn *scn);
DESCRIPTION
For a 32-bit class file,
elf32_getshdr
returns a pointer to a
section header for the section descriptor
scn.
Otherwise, the file is not a 32-bit class file,
scn
was null, or an error
occurred;
elf32_getshdr
then returns NULL.
The header includes the following members.
Elf32_Word sh_name;
Elf32_Word sh_type;
Elf32_Word sh_flags;
Elf32_Addr sh_addr;
Elf32_Off sh_offset;
Elf32_Word sh_size;
Elf32_Word sh_link;
Elf32_Word sh_info;
Elf32_Word sh_addralign;
Elf32_Word sh_entsize;
For a 64-bit class file,
elf64_getshdr
returns a pointer to a
section header for the section descriptor
scn.
Otherwise, the file is not a 64-bit class file,
scn
was null, or an error
occurred;
elf64_getshdr
then returns NULL.
The header includes the following members.
Elf64_Word sh_name;
Elf64_Word sh_type;
Elf64_Xword sh_flags;
Elf64_Addr sh_addr;
Elf64_Off sh_offset;
Elf64_Xword sh_size;
Elf64_Word sh_link;
Elf64_Word sh_info;
Elf64_Xword sh_addralign;
Elf64_Xword sh_entsize;
If the program is building a new file, it is responsible for
creating the file's ELF header before creating sections.
