verify function
Determine if one string contains a character that is not in the
other.

Calling Sequence
char *string1, *string2;
int verify(), offset;
offset = verify(string1, string2);
where string1 and string2 are pointers to character
strings ending in the null character ( 00).
Description
Use the verify function to determine if one character string
contains a character that the other does not.
Returns
The value of offset is -1 if all of the characters in string1 are
also in string2. Otherwise, the value is the offset of the first
character in string1 that is not in string2.

Example
/* Program test for the verify() function */
int offset, verify();
main(argc, argv)
int argc;
char *argv[];
{
offset = verify(argv[1], argv[2]);
if (offset == -1)
printf("'%s' contains all of '%s'\n",
argv[1], argv[2]);
