/*!
@brief
Split a string into tokens based on specified delimiters.

@param string
A pointer to a null-terminated string to be split into tokens.
@param delim
A pointer to a null-terminated string contained characters used to delimit
tokens.
@param tokens_buf
A pointer to the output token array.
@param max_tokens_buf
A pointer to the allocated size of the token array.
@param num_tokens_buf
A pointer to the number of elements in the token array.

@details
The memory to hold token information is allocated via jas_malloc()
and friends.

@returns
If successful, zero is returned.
Otherwise, a nonzero value is returned.
