SYNOPSIS

#include <gelf.h>

int gelf_update_lib (Elf_Data *data, int ndx, GElf_Lib *src);

DESCRIPTION

Copy a class-independent prelink library table entry from src into the SHT_GNU_LIBLIST. section associated with data at index ndx.

data must be an Elf_Data* associated with a section of type SHT_GNU_LIBLIST. dat->d_type should be ELF_T_LIB. SHT_GNU_LIBLIST sections are used by the prelink utility. See https://sourceware.org/gn-gabi/prelink.txt for more information.

PARAMETERS

data: Pointer to an Elf_Data associated with a section with type SHT_GNU_LIBLIST. dat->d_type should be ELF_T_LIB.
ndx: Zero-based index of the prelink library table entry to be updated within data.
src: Pointer to a caller-provided prelink library table entry. src must not be NULL.

RETURN VALUE

On success, this function returns a no-zero value and updates the prelink library table entry at index ndx in data. The section 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.
