= strtok =

== Syntax ==
{{char* strtok(void *str, const char *delimiters)}}

== Arguments ==
:'''str'''
::The string to tokenize.  On the second and repeated calls, this should be set to NULL to continue using the internal tokenizing buffer to search for the next token.
:'''delimiters'''
::A string of characters to use as delimiters (eg space, comma, tab symbol) that will split the string into tokens.

== Return ==
Returns a pointer to the internal string buffer pointing to the current token, or NULL if the end of the string has been reached with no more tokens found.

== Description ==
Splits a string into string "tokens", split by the given delimiters.  Each call to strtok returns a single token.

You can use this function to split a string into individual words by using the space character as a delimiter.  You might also use it to split a line of a CSV (comma-separated-value) file by using the comma symbol as a delimiter.

== Example ==
<code>
%fml

OnFilterStart: {
  char* strbuffer;
  char* token;
  strbuffer = malloc(1000);
  sprintf(strbuffer, "FM is awesome!");
  printf("%s", strbuffer);
  token = strtok(strbuffer, " ");
  while(token != NULL) {
    printf("%s", token);
    // Use NULL here, not strbuffer
    // otherwise infinite loop here!
    token = strtok(NULL, " ");
  }
  free(strbuffer);
  return true;
}
</code>
