Hi,

I have a question about linking with library.

Can I link my personal library first and then the standard library?
If so, how to do this?  Thank you very much.

Imagine I have a (large) legacy program that does not check the return
code of malloc.  I would like to link it to my personal library that
implements a wrapper for malloc (such as checking return code), then
link with the real standard library.  To illustrate this idea

legal code        my library                       standard library
  .......         
  malloc    -----> malloc()
  .......         {           |----------------->  malloc
                      if (malloc() == NULL)
                      .......
                  }

Platform: SunOS 5.6 and Linux 2.2.5
