-     <function>strtok</function> is used to tokenize a string.  That
-     is, if you have a string like "This is an example string" you
+     <function>strtok</function> splits a string (<parameter>arg1</parameter>)
+     into smaller strings (tokens), with each token being delimited by any 
+     character from <parameter>arg2</parameter>.
+     That is, if you have a string like "This is an example string" you
      could tokenize this string into its individual words by using the
      space character as the token.
