elf32_getphdr(3elf)

elf32_getphdr(3ELF)          ELF Library Functions         elf32_getphdr(3ELF)



NAME
       elf32_getphdr,  elf32_newphdr,  elf64_getphdr, elf64_newphdr - retrieve
       class-dependent program header table

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

       Elf32_Phdr *elf32_getphdr(Elf *elf);


       Elf32_Phdr *elf32_newphdr(Elf *elf, size_t count);


       Elf64_Phdr *elf64_getphdr(Elf *elf);


       Elf64_Phdr *elf64_newphdr(Elf *elf, size_t count);

DESCRIPTION
       For a 32-bit class file, elf32_getphdr() returns a pointer to the  pro‐
       gram execution header table, if one is available for the ELF descriptor
       elf.


       elf32_newphdr() allocates a new table with count entries, regardless of
       whether  one  existed  previously, and sets the ELF_F_DIRTY bit for the
       table. See elf_flagdata(3ELF).  Specifying  a  zero  count  deletes  an
       existing table. Note this behavior differs from that of elf32_newehdr()
       allowing a program to replace  or  delete  the  program  header  table,
       changing its size if necessary. See elf32_getehdr(3ELF).


       If no program header table exists, the file is not a 32-bit class file,
       an error occurs, or elf is NULL, both functions return a null  pointer.
       Additionally, elf32_newphdr() returns a null pointer if count is 0.


       The  table is an array of Elf32_Phdr structures, each of which includes
       the following members:

         Elf32_Word     p_type;
         Elf32_Off p_offset;
         Elf32_Addr     p_vaddr;
         Elf32_Addr     p_paddr;
         Elf32_Word     p_filesz;
         Elf32_Word     p_memsz;
         Elf32_Word     p_flags;
         Elf32_Word     p_align;



       The Elf64_Phdr structures include the following members:

         Elf64_Word     p_type;
         Elf64_Word     p_flags;
         Elf64_Off p_offset;
         Elf64_Addr     p_vaddr;
         Elf64_Addr     p_paddr;
         Elf64_Xword    p_filesz;
         Elf64_Xword    p_memsz;
         Elf64_Xword    p_align;



       For the 64−bit class, replace 32 with 64 as appropriate.


       The ELF header's e_phnum member tells  how  many  entries  the  program
       header  table  has. See elf32_getehdr(3ELF). A program may inspect this
       value to determine the size of an existing table; elf32_newphdr() auto‐
       matically  sets the member's value to count. If the program is building
       a new file, it is responsible for creating the file's ELF header before
       creating the program header table.
