ldgetpd(3x)															       ldgetpd(3x)

Name
       ldgetpd - retrieve procedure descriptor given a procedure descriptor index

Syntax
       #include <stdio.h>
       #include <filehdr.h>
       #include <sym.h>
       #include <ldfcn.h>

       long ldgetpd (ldptr, ipd, ppd)
       LDFILE ldptr;
       long ipd;
       pPDR ipd;

Description
       The  function  returns  success	or  failure  depending	on  whether the procedure descriptor with index ipd can be accessed.  If it can be
       accessed, the structure pointed to by ppd is filled with the contents of the corresponding procedure descriptor.  The isym, iline, and iopt
       fields  of the procedure descriptor are updated to be used in further LD routine calls. The adr field is updated from the symbol referenced
       by the isym field.

       The PDR cannot be retrieved when the following occurs:

       o    The procedure descriptor table cannot be found.

       o    The ipd offset into the procedure descriptor table is beyond the end of the table.

       o    The file descriptor that the ipd offset falls into cannot be found.

       Typically, is called while traversing the table that runs from 0 to SYMHEADER(ldptr).ipdMax - 1.
