Method
GioOutputStreamwrite_all
Declaration [src]
gboolean
g_output_stream_write_all (
GOutputStream* stream,
void* buffer,
gsize count,
gsize* bytes_written,
GCancellable* cancellable,
GError** error
)
Description [src]
Tries to write count
bytes from buffer
into the stream. Will block
during the operation.
This function is similar to g_output_stream_write(), except it tries to write as many bytes as requested, only stopping on an error.
On a successful write of count
bytes, TRUE
is returned, and bytes_written
is set to count
.
If there is an error during the operation FALSE
is returned and error
is set to indicate the error status.
As a special exception to the normal conventions for functions that
use GError
, if this function returns FALSE
(and sets error
) then
bytes_written
will be set to the number of bytes that were
successfully written before the error was encountered. This
functionality is only available from C. If you need it from another
language then you must write your own loop around g_output_stream_write().
Parameters
buffer
-
Type: An array of
guint8
The buffer containing the data to write.
The length of the array is specified in the count
argument.The data is owned by the caller of the method. count
-
Type:
gsize
The number of bytes to write.
bytes_written
-
Type:
gsize*
Location to store the number of bytes that was written to the stream.
The argument will be set by the function. The argument can be NULL
. cancellable
-
Type:
GCancellable
Optional
GCancellable
object,NULL
to ignore.The argument can be NULL
.The data is owned by the caller of the method. error
-
Type:
GError **
The return location for a recoverable error.
The argument can be NULL
.If the return location is not NULL
, then you must initialize it to aNULL
GError*
.The argument will be left initialized to NULL
by the method if there are no errors.In case of error, the argument will be set to a newly allocated GError
; the caller will take ownership of the data, and be responsible for freeing it.
