elf_fill(S-osr5)

elf_fill -- set fill byte

Syntax

cc [flag . . . ] file . . . -lelf [library] . . .


#include <libelf.h>

void elf_fill(int fill);

Description

This command lets you set the data fill character.

Alignment constraints for ELF files sometimes require the presence of ``holes.'' For example, if the data for one section are required to begin on an eight-byte boundary, but the preceding section is too ``short,'' the library must fill the intervening bytes.

These bytes are set to the fill character. The library uses zero bytes unless the application supplies a value. See elf_getdata(S-osr5) for more information about those holes.

Diagnostics

Error conditions are identified through the routine elf_error(S-osr5).

Warning

An application can assume control of the object file organization by setting the bit ELF_F_LAYOUT (see elf_flag(S-osr5)). When the bit is set, the library does not fill holes.
