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 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.
POSIX.1-2001, POSIX.1-2008, SVr4, 4.3BSD. Present in libc since libc-4.6.27.
The naming is unfortunate.
