|
* This function does a binary search on the given array. The |
|
* contents of the array should already be in ascending sorted order |
|
* under the provided comparison function. |
|
* |
|
* Note that the key need not have the same type as the elements in |
|
* the array, e.g. key could be a string and the comparison function |
|
* could compare the string with the struct's name field. However, if |
|
* the key and elements in the array are of the same type, you can use |
|
* the same comparison function for both sort() and bsearch(). |
