SYNOPSYS
#include "mut.h"
int gethtitem(table, key)
ht *table;
void *key;
PARAMETERS
table Hash table pointer
key Key used by the hash coding function
DESCRIPTION
gethtitem() searches an item in the hash table pointed to by table.
RETURN VALUE
If the key key exists, the associated value is returned, if it doesn't, the function returns EMPTYHT.
EXAMPLE
#include <stdio.h>
#include "mut.h"
check(p)
losig_list *p;
{
char *amatla;
losig_list *ptsig;
locon_list *ptcon;
ht *h;
for (i = 0, ptsig = p->LOSIG; ptsig; i++, ptsig = ptsig->NEXT);
h = addht(i);
/* two connectors can't have the same name! */
for (ptcon = p->LOCON; ptcon; ptcon = ptcon->NEXT)
addhtitem(h, ptcon->NAME, 0);
for (ptsig = p->LOSIG; ptsig; ptsig = ptsig->NEXT) {
if (ptsig->TYPE == INTERNAL) {
amatla = getsigname(ptsig);
/* this is nicely done with sethtitem! */
if (gethtitem(h, amatla) == EMPTYHT) {
printf("N %s;
", amatla);
addhtitem(h, amatla, 0);
}
}
}
delht();
}
