- * 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.
