*
* This routine takes a pointer to an array of ptrcnt character pointers.
* It will place a pointer to each attribute of the current host into
* this array. The pointers are pointing to a static buffer, so they
* should be copied if necessary. The routine returns -1 on error, or
* the number of pointers placed in the array. In addition, the pointer
* after the last pointer used is set to NULL if there is room in the
* array.
