Section (3) lsearch
lfind, lsearch — linear search of an array
||const void *key,|
|const void *base,|
||const void *key,|
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.
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.
lfind() returns a pointer to
a matching member of the array, or NULL if no match is found.
lsearch() returns a pointer to
a matching member of the array, or to the newly added member
if no match is found.
