Definition at line 103 of file elf.h.

◆ e_ehsize

Elf64_Half Elf64_Ehdr::e_ehsize

Size of this header in bytes, should be sizeof(Elf64_Ehdr)

Definition at line 104 of file elf.h.

◆ e_phentsize

Elf64_Half Elf64_Ehdr::e_phentsize

Size in bytes of one entry in the files program header table.

Definition at line 105 of file elf.h.

◆ e_phnum

Elf64_Half Elf64_Ehdr::e_phnum

Number of entries in the program header table.

Definition at line 106 of file elf.h.

◆ e_shentsize

Elf64_Half Elf64_Ehdr::e_shentsize

Size in bytes of one entry in the files section header table.

Definition at line 107 of file elf.h.

◆ e_shnum

Elf64_Half Elf64_Ehdr::e_shnum

Number of entries in the section header table, or 0 if there are no section headers.

If the number of sections is greater than or equal to SHN_LORESERVE (0xff00), this field contains 0 and the actual number of section header table entires is contained in the sh_size field of section header index 0.

Definition at line 114 of file elf.h.

◆ e_shstrndx

Elf64_Half Elf64_Ehdr::e_shstrndx

Section header table index of the entry associated with the section name string table, or SHN_UNDEF if there are no section names.

If the section name string table section index is greater than or equal to SHN_LORESERVE (0xff00), this field contains SHN_XINDEX(0xffff) and the actual section index is contained in the sh_link field of section header index 0.
