ELF32\_NEWPHDR(3) Libelf Programmer's Manual ELF32\_NEWPHDR(3) # [NAME](#NAME) elf32\_newphdr, elf64\_newphdr - create a new program header table for a 32-bit or 64-bit ELF object file # [SYNOPSIS](#SYNOPSIS) ``` #include Elf32_Phdr *elf32_newphdr(Elf *elf, size_t count); Elf64_Phdr *elf64_newphdr(Elf *elf, size_t count); ``` # [DESCRIPTION](#DESCRIPTION) Create a new program header table for the ELF object file referred to by *elf*. The number of entries in the new program header table is specified by *count*. A *count* of zero removes the existing program header table. The function allocates a new array of **Elf32\_Phdr** and makes it the program header table for *elf*. The new program header contents are set to zero and any previous program header table is discarded. An ELF header must exist before creating a program header table. # [PARAMETERS](#PARAMETERS) [*elf*](#elf) Pointer to the ELF object for which a new program header table is to be created. [*count*](#count) The number of entries in the new program header table. A count of zero removes the existing program header table. # [RETURN VALUE](#RETURN_VALUE) On success, return a pointer to the first **Elf32\_Phdr** in the newly created program header table. If *elf* is NULL then return NULL. If an error occurs, return NULL and set a libelf error code. # [SEE ALSO](#SEE_ALSO) [**elf32\_newehdr**(3)](/man/os/elfutils/elf32_newehdr.3), [**elf\_errno**(3)](/man/os/elfutils/elf_errno.3), [**libelf**(3)](/man/os/elfutils/libelf.3), [**elf**(5)](/man/os/elfutils/elf.5) # [ATTRIBUTES](#ATTRIBUTES) For an explanation of the terms used in this section, see [**attributes**(7)](/man/os/elfutils/attributes.7). **Interface** **Attribute** **Value** elf32\_newphdr (), elf64\_newphdr () Thread safety MT-Safe # [REPORTING BUGS](#REPORTING_BUGS) Report bugs to <elfutils-devel@sourceware.org> or https://sourceware.org/bugzilla/. 2024-08-14 Libelf --- Document: elf32_newphdr(3) from elfutils 0.197-r0 (Chainguard OS) Source: https://sourceware.org/git/elfutils.git
