But it is likely that AppNee will make an evolution in a few years. And in AppNee's current running mode, this would take 13 years at least. Instead, please make a check by yourself then.ġ) To finish AppNee's original mission, we still have 3500+ applications to share. For now we won't remind you by replying your email as before. Then we will try to fix all mentioned links ASAP (that usually takes 7+ days). In the main function the target array is sorted with qsort before calling bsearch to search for a value.Please feedback any invalid download links you met at AppNee via E-mail, must including post URL and missing file link(s). In the example, compareints compares the values pointed to by the two parameters as int values and returns the result of subtracting their pointed values, which gives 0 as result if they are equal, a positive result if the value pointed to by a is greater than the one pointed to by b or a negative result if the value pointed to by b is greater. Printf ( "%d is not in the array.\n",key) Printf ( "%d is in the array.\n",*pItem) PItem = ( int*) bsearch (&key, values, 6, sizeof ( int), compareints) Qsort (values, 6, sizeof ( int), compareints)
* bsearch example */ #include /* printf */ #include /* qsort, bsearch, NULL */ int compareints ( const void * a, const void * b) This function is called repeatedly by bsearch to compare key against individual elements in base. compar Pointer to a function that compares two elements. size Size in bytes of each element in the array. num Number of elements in the array pointed to by base. base Pointer to the first object of the array where the search is performed, type-casted to a void*.
Parameters key Pointer to the object that serves as key for the search, type-casted to a void*. This requirement is fulfilled by any array ordered with the same criteria used by compar (as if sorted with qsort). To perform the search, the function performs a series of calls to compar with key as first argument and elements of the array pointed to by base as second argument.īecause this function may be optimized to use a non-linear search algorithm (presumably a binary search), the elements that compare less than key using compar should precede those that compare equal, and these should precede those that compare greater. Searches the given key in the array pointed to by base (which is formed by num elements, each of size bytes), and returns a void* pointer to a matching element, if found.
