Detailed Description

Function definitions for ELF relocation utility.

Author:

D.L. Wood

These functions implement the ELF object file relocation utility. The user provides an input file name and an output file name. After removing the local relocation entries, the stripped ELF object is written to output. All of the relevant size and index information in the section headers is adjusted to reflect the removals.
