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

This function is similar to, 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.

As a special exception to the normal conventions for functions that use GError, if this function returns FALSE (and sets error) then bytes_read will be set to the number of bytes that were successfully read 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

class InputStream
out ubyte[] buffer
out size_t bytesRead


buffer ubyte[]

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

bytesRead size_t

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