- *
- * Function : ssplit
- *
- * Description : Split a string using delimiters in `delim'. Results
- * go into `vec'.
- *
- * Parameters :
- * 1 : str = string to split. Will be split in place
- * (i.e. do not free until you've finished with vec,
- * previous contents will be trashed by the call).
- * 2 : delim = array of delimiters (if NULL, uses " \t").
- * 3 : vec[] = results vector (aka. array) [out]
- * 4 : vec_len = number of usable slots in the vector (aka. array size)
- * 5 : dont_save_empty_fields = zero if consecutive delimiters
- * give a null output field(s), nonzero if they are just
- * to be considered as single delimeter
- * 6 : ignore_leading = nonzero to ignore leading field
- * separators.
- *
- * Returns : -1 => Error: vec_len is too small to hold all the
- * data, or str == NULL.
- * >=0 => the number of fields put in `vec'.
- * On error, vec and str may still have been overwritten.
- *
