<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.
|
||||
<example>
