ldptr(S)

allocldptr, freeldptr, vldldptr -- ldptr structure usage routines

Syntax

cc . . . -lld

#include <ldfcn.h>

LDFILE * allocldptr ()

int freeldptr (ldptr)
LDFILE *ldptr;

int vldldptr (ldptr)
LDFILE *ldptr;

Description

allocldptr- allocate ldptr structure and add to linked list

freeldptr- free allocated ldptr structure from linked list

vldldptr- verify ldptr structure on linked list

The allocldptr routine allocates an LDFILE structure in memory and attaches it to the end of a linked list of such structures. allocldptr returns a pointer to the newly allocated LDFILE structure.

freeldptr takes an instance of the LDFILE structure pointed to by ldptr and deletes it from the linked list.

vldldptr determines if the LDFILE structure pointed to by ldptr is in the linked list and returns SUCCESS if the structure is in the linked list.

Return values

allocldptr returns a pointer to the newly allocated LDFILE structure on success; otherwise, NULL is returned.

freeldptr and vldldptr both return SUCCESS on success; otherwise, they return FAILURE.

Standards conformance

allocldptr, freeldptr, and vldldptr are not part of any currently supported standard; they are an extension of AT&T System V provided by the Santa Cruz Operation.
