bsearch
() function searches an array of
nmemb objects, the initial member of which is pointed to
by base, for a member that matches the object pointed to
by key. The size of each member of the array is
specified by size.
The contents of the array should be in ascending sorted order according to the comparison function referenced by compar. The compar routine is expected to have two arguments which point to the key object and to an array member, in that order, and should return an integer less than, equal to, or greater than zero if the key object is found, respectively, to be less than, to match, or be greater than the array member.
bsearch
() function returns a pointer to a matching
member of the array, or a null pointer if no match is found. If two members
compare as equal, which member is matched is unspecified.
bsearch
() function conforms to ANSI
X3.159-1989 (“ANSI C89”).
