lsearch

pointer-to-element.

Undeﬁned results can occur if there is not enough room in the table to add a new item.

Example

This fragment reads in TABSIZE strings of length ELSIZE and stores them in a table,

eliminating duplicates.

#include stdio.h>

#include search.h>

#define TABSIZE 50

#define ELSIZE 120

char line[ELSIZE], tab[TABSIZE][ELSIZE], *lsearch( );

unsigned nel = 0;

int strcmp( );

…

while (fgets(line, ELSIZE, stdin) != NULL

nel TABSIZE)

(void) lsearch(line, (char *)tab,nel,

ELSIZE, strcmp);
