Gio.InputStream.prototype.read_all

function read_all(buffer: ByteArray, cancellable: Gio.Cancellable): [ok: Boolean, bytes_read: Number(gsize)] {
    // Gjs wrapper for g_input_stream_read_all()
}
  

Tries to read count bytes from the stream into the buffer starting at buffer. Will block during this read.

This function is similar to Gio.InputStream.prototype.read, except it tries to read as many bytes as requested, only stopping on an error or end of stream.

On a successful read of count bytes, or if we reached the end of the stream, true is returned, and bytes_read is set to the number of bytes read into buffer.

If there is an error during the operation false is returned and @error is set to indicate the error status, bytes_read is updated to contain the number of bytes read into buffer before the error occurred.

buffer

a buffer to read data into (which should be at least count bytes long).

cancellable

optional Gio.Cancellable object, null to ignore.

ok

true on success, false if there was an error

bytes_read

location to store the number of bytes that was read from the stream
