Parameters: API   the API handle out   descriptor for a file stream; or zero to write to memory wmf_stream_create() creates a wmfStream (a character-based output stream) for output to a file or, if out is zero, to memory. Returns: Returns a wmfStream pointer, or zero on failure. Possible library error states of wmf_E_InsMem or wmf_E_BadFile. void wmf_stream_destroy (  wmfAPI * API, wmfStream * stream, char ** buffer, unsigned long * length )    Close an uncompressed character output stream. Parameters: API   the API handle stream   stream handle buffer   for memory return length   for length return In the case of write-to-memory, on return *buffer is an array of length length. int wmf_stream_printf (  wmfAPI * API, wmfStream * stream, char * format, ... )    Formatted print to character output stream. Parameters: API   the API handle stream   stream handle format   print format With syntax similar to printf(), wmf_stream_printf() prints a formatted message to a wmfStream character stream. Returns: Returns the number of characters written, or zero on failure. Possible library error state of wmf_E_InsMem. int wmf_stream_reset (  void * context )    For internal use only. int wmf_stream_rezet (  void * context )    For internal use only. int wmf_stream_sputs (  char * str, void * context )    For internal use only. int wmf_stream_zputs (  char * str, void * context )    For internal use only. wmfStream* wmf_ztream_create (  wmfAPI * API, gzFile out )    Open a compressed character output stream. Parameters: API   the API handle out   descriptor for a zlib compressed file stream wmf_ztream_create() creates a wmfStream (a character-based output stream) for output to a file opened via zlib. (Writing compressed data to memory is not currently supported.) Returns: Returns a wmfStream pointer, or zero on failure. Possible library error state of wmf_E_InsMem. void wmf_ztream_destroy (  wmfAPI * API, wmfStream * stream, char ** buffer, unsigned long * length )    Close a compressed character output stream. Parameters: API   the API handle stream   stream handle buffer   (unused) length   (unused)
