Method
GioOutputStreamvprintf
since: 2.40
Declaration
gboolean
g_output_stream_vprintf (
GOutputStream* stream,
gsize* bytes_written,
GCancellable* cancellable,
GError** error,
const gchar* format,
va_list args
)
Description
This is a utility function around g_output_stream_write_all(). It
uses g_strdup_vprintf() to turn format and args into a string that
is then written to stream.
See the documentation of g_output_stream_write_all() about the
behavior of the actual write operation.
Note that partial writes cannot be properly checked with this
function due to the variable length of the written string, if you
need precise control over partial write failures, you need to
create you own printf()-like wrapper around g_output_stream_write()
or g_output_stream_write_all().
Available since: 2.40
This method is not directly available to language bindings.
