59/* Code for dynamic hash table routines
60 * Author - Eric Young v 2.0
61 *
62 * 2.2 eay - added #include "crypto.h" so the memory leak checking code is
63 * present. eay 18-Jun-98
64 *
65 * 2.1 eay - Added an 'error in last operation' flag. eay 6-May-98
66 *
67 * 2.0 eay - Fixed a bug that occurred when using lh_delete
68 * from inside lh_doall(). As entries were deleted,
69 * the 'table' was 'contract()ed', making some entries
70 * jump from the end of the table to the start, there by
71 * skipping the lh_doall() processing. eay - 4/12/95
72 *
73 * 1.9 eay - Fixed a memory leak in lh_free, the LHASH_NODEs
74 * were not being free()ed. 21/11/95
75 *
76 * 1.8 eay - Put the stats routines into a separate file, lh_stats.c
77 * 19/09/95
78 *
79 * 1.7 eay - Removed the fputs() for realloc failures - the code
80 * should silently tolerate them. I have also fixed things
81 * lint complained about 04/05/95
82 *
83 * 1.6 eay - Fixed an invalid pointers in contract/expand 27/07/92
84 *
85 * 1.5 eay - Fixed a misuse of realloc in expand 02/03/1992
86 *
87 * 1.4 eay - Fixed lh_doall so the function can call lh_delete 28/05/91
88 *
89 * 1.3 eay - Fixed a few lint problems 19/3/1991
90 *
91 * 1.2 eay - Fixed lh_doall problem 13/3/1991
92 *
93 * 1.1 eay - Added lh_doall
94 *
95 * 1.0 eay - First version
