Tries to write the bytes contained in the n_vectors vectors into the stream. Will block during the operation.

This function is similar to OutputStream.writev, except it tries to write as many bytes as requested, only stopping on an error.

On a successful write of all n_vectors vectors, TRUE is returned, and bytes_written is set to the sum of all the sizes of vectors.

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 OutputStream.write.

The content of the individual elements of vectors might be changed by this function.

class OutputStream


vectors GOutputVector[]

the buffer containing the GOutputVectors to write.

bytesWritten size_t

location to store the number of bytes that were written to the stream

cancellable Cancellable

optional gio.Cancellable object, NULL to ignore.

Return Value

Type: bool

TRUE on success, FALSE if there was an error


GException on failure.
