Answer : strstr

You may want to consider using strcspn.
 -- "Get span of character set in string"

 -- "Returns the length of the initial portion of str1 which consists only of characters that are part of str2."


For example:
   char sentence[] = "this is a string ";
   int pos = strcspn( sentence, " ");
In this case pos will be 4, so you know that sentence[0] through sentence[3] are not blanks. You can then use strncpy with a count of 4 to copy out the first 4 chars into your token buffer (and then add null byte).
