ldgetaux - retrieves an auxiliary entry
#include <stdio.h> #include <filehdr.h> #include <sym.h>
#include <ldfcn.h>
pAUXU ldgetaux(
LDFILE ldptr,
long iaux );
The ldgetaux() routine returns a pointer to the auxiliary
table entry (AUXU) indexed by iaux. The entry is contained
in a static buffer. Because the buffer can be overwritten
by later calls to ldgetaux(), the entry must be
copied by the caller if it is to be saved or changed.
Note that auxiliary table entries are not swapped. If
LDAUXSWAP(ldptr,ldf) is nonzero, a further call to
swap_aux() is required. Before calling the swap_aux() routine,
the caller should copy the entry.
If the auxiliary table entry cannot be retrieved,
ldgetaux() returns NULL. This occurs when: The auxiliary
table cannot be found The iaux offset into the auxiliary
table is beyond the end of the table
The ltdbread() routine returns a local symbol (SYMR)
structure that may contain an index into the auxiliary
table. If so, ldgetaux() can be called with this index to
retrieve data type information for the local symbol. If
the data type information for a symbol is not present,
ldgetaux() should not be called.
The program must be loaded with the object file access
routine library libmld.a.
