ldgetpd - retrieves procedure descriptor given a procedure
#include <stdio.h> #include <filehdr.h> #include <sym.h>
pPDR ppd );
The ldgetpd() routine returns a 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 procedure descriptor
table cannot be found. The ipd offset into the procedure
descriptor table is beyond the end of the table. The file
descriptor that the ipd offset falls into cannot be found.
Typically, ldgetpd() is called while traversing the table
that runs from 0 to SYMHEADER(ldptr).ipdMax - 1.
The program must be loaded with the object file access
routine library libmld.a.
