atol (Continued)
Example:
bsearch
Description:

Arguments:
Return Value:
Remarks:
#include <stdio.h>
#include <stdlib.h> /* for atol
int main(void)
{
}
Output:
String = " -123456"
String = "2Number"
Performs a binary search
<stdlib.h>
void *bsearch(const void *key, const void *base,
key
base
nelem
size
cmp
ck
ce
Returns a pointer to the object being searched for if found; otherwise,
returns NULL.
The value returned by the compare function is <0 if ck is less than ce,
0 if ck is equal to ce, or >0 if ck is greater than ce.
In the following example, qsort is used to sort the list before bsearch
is called. bsearch requires the list to be sorted according to the com-
parison function. This comp uses ascending order.

int (*cmp)(const void *ck, const void *ce));
char a[] = " -123456";
char b[] = "2Number";
long x;
x = atol(a);
printf("String = \"%s\"
x = atol(b);
printf("String = \"%s\"
