gelf_newehdr - Man Page
allocate and initialize a new ELF file header
Synopsis
#include <gelf.h> void *gelf_newehdr(Elf *elf, int class);
Description
gelf_newehdr() allocates and initializes a new ELF header for elf, if a header does not already exist. When a new ELF header is created, all of its fields are zero-initialized.
The caller must specify the ELF class via class, which must be either:
- ELFCLASS32
Request a 32-bit ELF file header.
- ELFCLASS64
Request a 64-bit ELF file header.
Parameters
- elf
Pointer to an ELF descriptor of kind ELF_K_ELF.
- class
The requested ELF class for the new header. Must be ELFCLASS32 or ELFCLASS64.
Return Value
On success, gelf_newehdr() will return a non-zero value. The ELF header of elf can be retrieved using gelf_getehdr(). elf32_getehdr() or elf64_getehdr() can also be used depending on the ELF class specified by class.
On failure, NULL is returned and elf_errno is set. If elf is NULL then NULL is returned without setting elf_errno.
In other libelf implementations the gelf_newehdr() return value may be a different type.
