lfind, lsearch - linear search of an array
#include <search.h> void *lfind(const void *key, const void *base, size_t *nmemb, size_t size, int(*compar)(const void *, const void *)); void *lsearch(const void *key, void *base, size_t *nmemb, size_t size, int(*compar)(const void *, const void *));
lfind() and lsearch() perform a linear search for
key in the array
base which has
*nmemb elements of
size bytes each. The comparison function referenced by
compar is expected to have two arguments which point to the
key object and to an array member, in that order, and which returns zero if the
key object matches the array member, and nonzero otherwise.
If lsearch() does not find a matching element, then the
key object is inserted at the end of the table, and
*nmemb is incremented. In particular, one should know that a matching element exists, or that more room is available.
For an explanation of the terms used in this section, see attributes(7).
