RELOC(4)             INTERACTIVE UNIX System             RELOC(4)



          NAME
               reloc - relocation information for a common object file

          SYNOPSIS
               #include  <reloc.h>

          DESCRIPTION
               Object files have one relocation entry for each relocatable
               reference in the text or data.  If relocation information is
               present, it will be in the following format.

                 struct       reloc
                 {
                      long    r_vaddr ;/* (virtual) address of reference */
                      long    r_symndx ;/* index into symbol table */
                      short   r_type ;/* relocation type */
                 } ;
                 # define R_PCRLONG  024

               As the link editor reads each input section and performs
               relocation, the relocation entries are read.  They direct
               how references found within the input section are treated.

               R_PCRLONG   A "PC-relative" 32-bit reference to the symbol's
                           virtual address.

               More relocation types exist for other processors.
               Equivalent relocation types on different processors have
               equal values and meanings.  New relocation types will be
               defined (with new values) as they are needed.

               Relocation entries are generated automatically by the assem-
               bler and automatically used by the link editor.  Link editor
               options exist for both preserving and removing the reloca-
               tion entries from object files.
