elf32_newphdr, elf64_newphdr, gelf_newphdr -- allocate an ELF program header table
ELF Access Library (libelf, -lelf)
#include <libelf.h> Elf32_Phdr * elf32_newphdr(Elf *elf, size_t count); Elf64_Phdr * elf64_newphdr(Elf *elf, size_t count); #include <gelf.h> void * gelf_newphdr(Elf *elf, size_t count);
These functions allocate an ELF Program Header table for an ELF descriptor. Elf32_Phdr and Elf64_Phdr descriptors are described further in elf(5). Functions elf32_newphdr() and elf64_newphdr() allocate a table of count Elf32_Phdr and Elf64_Phdr descriptors respectively, discarding any existing program header table already present in the ELF descriptor elf. A value of zero for argument count may be used to delete an exist- ing program header table from an ELF descriptor. Function gelf_newphdr() will return a table of Elf32_Phdr or Elf64_Phdr with count elements depending on the ELF class of ELF descriptor elf. The functions set the ELF_F_DIRTY flag on the program header table. All members of the returned array of Phdr structures will be initialized to zero. After a successful call to these functions, the pointer returned by a prior call to elf32_getphdr() or elf64_getphdr() on the same descriptor elf will no longer be valid.
The functions a valid pointer if successful, or NULL in case an error was encountered.
These functions may fail with the following errors: [ELF_E_ARGUMENT] Argument elf was NULL. [ELF_E_ARGUMENT] Argument elf was not a descriptor for an ELF object. [ELF_E_CLASS] ELF descriptor elf was of an unrecognized class. [ELF_E_RESOURCE] An out of memory condition was detected. [ELF_E_SEQUENCE] An executable header was not allocated for ELF descriptor elf before using these APIs.
