DataInputStream.readUpto

string readUpto(string stopChars, out size_t length, gio.cancellable.Cancellable cancellable = null)

Reads a string from the data input stream, up to the first occurrence of any of the stop characters.

In contrast to [gio.data_input_stream.DataInputStream.readUntil], this function does not consume the stop character. You have to use [gio.data_input_stream.DataInputStream.readByteData] to get it before calling [gio.data_input_stream.DataInputStream.readUpto] again.

Note that stop_chars may contain '\0' if stop_chars_len is specified.

The returned string will always be nul-terminated on success.

Parameters

`stopChars`	characters to terminate the read
`length`	a #gsize to get the length of the data read in
`cancellable`	optional #GCancellable object, null to ignore

Returns

a string with the data that was read

before encountering any of the stop characters. Set length to a #gsize to get the length of the string. This function will return null on an error

Throws

[ErrorWrap]
