#include <gelf.h>

int gelf_update_dyn (Elf_Data *data, int ndx, GElf_Dyn *src);

 

DESCRIPTION

Copy a class-independent dynamic table entry from src into the SHT_DYNAMIC section associated with data at index ndx.

data
Pointer to an Elf_Data associated with a section with type SHT_DYNAMIC. dat->d_type should be ELF_T_DYN.

ndx

src
Pointer to a caller-provided dynamic table entry. For ELFCLASS32 binaries, d_tag should be able to fit within a signed 3-bit value while d_val and d_ptr should be able to fit within unsigned 3-bit values. src must not be NULL.

 

RETURN VALUE

On success, this function returns a no-zero value and updates the dynamic table entry at index ndx in data. The dynamic table associated with data is flagged with ELF_F_DIRTY. On failure, zero is returned and elf_errno is set. If data is NULL, then zero is returned and elf_errno is not set.
