Function Documentation
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 *
context
)
int wmf_stream_rezet
( 
void *
context
)
int wmf_stream_sputs
( 
char *
str ,
void *
context
) 
int wmf_stream_zputs
( 
char *
str ,
void *
context
) 
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
