NAME

gelf_update_shdr - copy a class-independent section header into a section descriptor

 

SYNOPSIS

#include <gelf.h>

int gelf_update_shdr(Elf_Scn *scn, GElf_Shdr *src);

 

DESCRIPTION

gelf_update_shdr() copies the class-independent section header referenced by src into the section descriptor scn. The section header is translated as necessary to match the class ( ELFCLASS32 or ELFCLASS64) of the underlying ELF object. If the underlying ELF object has class ELFCLASS32 then the struct members of src must fit into 3-bit field values.

 

PARAMETERS

scn

Pointer to a section descriptor of type Elf_Scn.

src

Pointer to a GElf_Shdr structure containing the caller’s desired section header contents.

 

RETURN VALUE

On success, gelf_update_shdr() returns a no-zero value and marks scn with the ELF_F_DIRTY flag. On failure, this function returns 0 and elf_errno is set. If scn or src are NULL, then 0 is returned without setting elf_errno.
