Function Documentation

wmfStream* wmf_stream_create (  wmfAPI *    API, FILE *    out )

Open an uncompressed character output stream. 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 *    )

uncompressed char output (wmf_stream_create): rewind()

int wmf_stream_rezet (  void *    )

compressed char output (wmf_ztream_create): rewind()

int wmf_stream_sputs (  char *   , void *    )

uncompressed char output (wmf_stream_create): fputs()

int wmf_stream_zputs (  char *   , void *    )

compressed char output (wmf_ztream_create): fputs()

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)
