/***
*char *_strdup(string) - duplicate string into malloc'd memory
*
*Purpose:
*       Allocates enough storage via malloc() for a copy of the
*       string, copies the string into the new memory, and returns
*       a pointer to it.
*
*Entry:
*       char *string - string to copy into new memory
*
*Exit:
*       returns a pointer to the newly allocated storage with the
*       string in it.
*
*       returns NULL if enough memory could not be allocated, or
*       string was NULL.
*
*Uses:
