elf_fill(3elf)

elf_fill -- set fill byte

Synopsis

   cc [flag . . . ] file . . . -lelf [library] . . .
   
   #include <libelf.h>
   

   void elf_fill(int fill);

Description

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(3elf) for more information about these holes.

Notices

An application can assume control of the object file organization by setting the ELF_F_LAYOUT bit [see elf_flag(3elf)]. When this is done, the library does not fill holes.
