|
.B Qsort
|

is an implementation of the quicker-sort algorithm.
|
||
|
|
The first argument is a pointer to the base of the data;
|
||
|
|
the second is the number of elements;
|
||
|
|
the third is the width of an element in bytes;
|
||
|
|
the last is the name of the comparison routine
|
||
|
|
to be called with two arguments which are pointers
|
||
|
|
to the elements being compared.
|
||
|
|
The routine must return an integer less than, equal to, or greater than 0
|
||
|
|
according as the first argument is to be considered
|
||
|
|
less than, equal to, or greater than the second.
