void g_mime_stream_construct (GMimeStream *stream, GMimeStream *stream_template, unsigned int type, |
Initializes a new stream of type type, using the virtual methods from stream_template, with bounds start and end.
|
Attempts to read up to len bytes from stream into buf.
|
Attempts to write up to len bytes of buf to stream.
|
Repositions the offset of the stream stream to the argument offset according to the directive whence as follows:
GMIME_STREAM_SEEK_SET: The offset is set to offset bytes.
GMIME_STREAM_SEEK_CUR: The offset is set to its current location plus offset bytes.
GMIME_STREAM_SEEK_END: The offset is set to the size of the stream plus offset bytes.
|
Gets the current offset within the stream.
|
Tests the end-of-stream indicator for stream.
|
Gets the length of the stream.
GMimeStream* g_mime_stream_substream (GMimeStream *stream, |
Creates a new substream of stream with bounds start and end.
void g_mime_stream_set_bounds (GMimeStream *stream, |
Set the bounds on a stream.
|
Writes string to stream.
|
Write formatted output to a stream.
|
Attempts to write stream src to stream dest.
|
Writes at most count blocks described by vector to stream.
