Function Documentation

◆ rtems_rtl_elf_file_check()

bool rtems_rtl_elf_file_check ( rtems_rtl_obj obj,
int  fd 
)

The ELF format check handler.

Parameters
objThe object being checked.
fdThe file descriptor.

◆ rtems_rtl_elf_file_load()

bool rtems_rtl_elf_file_load ( rtems_rtl_obj obj,
int  fd 
)

The ELF format load handler.

Parameters
objThe object to load.
fdThe file descriptor.

◆ rtems_rtl_elf_file_sig()

rtems_rtl_loader_format* rtems_rtl_elf_file_sig ( void  )

The ELF format signature handler.

Returns
rtems_rtl_loader_format* The format's signature.

◆ rtems_rtl_elf_file_unload()

bool rtems_rtl_elf_file_unload ( rtems_rtl_obj obj)

The ELF format unload handler.

Parameters
objThe object to unload.

◆ rtems_rtl_obj_relocate_unresolved()

bool rtems_rtl_obj_relocate_unresolved ( rtems_rtl_unresolv_reloc reloc,
rtems_rtl_obj_sym sym 
)

Relocate an object file's unresolved reference.

Parameters
recThe unresolved relocation record.
symThe unresolved relocation's referenced symbol.
Return values
trueThe object file record was relocated.
falseThe relocation failed. The RTL error is set.
