\brief Separate a string into arguments in an array
\param buf The string to be parsed (this must be a writable copy, as it will be modified)
\param delim The character to be used to delimit arguments
\param array An array of 'char *' to be filled in with pointers to the found arguments
\param arraylen The number of elements in the array (i.e. the number of arguments you will accept)
Note: if there are more arguments in the string than the array will hold, the last element of
the array will contain the remaining arguments, not separated.
\return The number of arguments found, or zero if the function arguments are not valid.
