ldgetpd(3)ldgetpd(3)NAMEldgetpd - retrieves procedure descriptor given a procedure descriptor
index
SYNOPSIS
#include <stdio.h> #include <filehdr.h> #include <sym.h> #include
<ldfcn.h>
long ldgetpd(
LDFILE ldptr,
long ipd,
pPDR ppd );
DESCRIPTION
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.
