lfind, lsearch - linear search of an array
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
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.
POSIX.1-2001, POSIX.1-2008, SVr4, 4.3BSD. Present in libc since libc-4.6.27.
The naming is unfortunate.
