RELOC(F)                             UNIX System V



     Name
          reloc - relocation information for a common object file


     Syntax
          #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
          assembler  and  automatically used by the link editor.  Link
          editor options exist for both preserving  and  removing  the
          relocation entries from object files.
