.SH SYNOPSYS
.if n \{\
.ft B \}
.if t \{\
.ft CR \}
.nf
#include "mut.h"
void addhtitem(table, key, value)
ht \(**table;
void \(**key;
int value;
.fi

.SH PARAMETERS
.TP 20
\fItable\fP
Hash table pointer
.TP 20
\fIkey\fP
Key used by the hash coding function to add the item
.TP 20
\fIvalue\fP
Value associated with the key
.SH DESCRIPTION
\fBaddhtitem()\fP adds a new item in the hash table pointed to by \fItable\fP.
If the key already exists, the old value is changed to the new one.
\fIValue\fP must be distinct from \fBEMPTYHT\fP and \fBDELETEHT\fP.
The length of the table increases automatically when the length given
in \fBaddht()\fP leads to a performance shut down.

.RS
The values \fBEMPTYHT\fP, \fI-1\fP,  and \fBDELETEHT\fP, \fI-2\fP,
are reserved for internal use, sorry.
.SH DIAGNOSTICS
