Member Function Documentation

await_char()

gate_result_t await_char	(	gate_char32_t *	ptr_char,
		gate_uint32_t	timeout_ms )

Awaits the availabilty of a character to be read from the input stream or until a timeout is reached.

Parameters

[out]	ptr_char	Pointer to UTF-32 character that is filled with retrieved input
[in]	timeout_ms	Timeout in milliseconds to wait for and to return GATE_RESULT_TIMEOUT

Returns

GATE_RESULT_* result code (OK = character ready to be read, TIMEOUT = no character available)

read_char()

gate_result_t read_char

(

gate_char32_t *

ptr_char

)

Reads a single input character from the console in a given time range.

Parameters

[out]

ptr_char

Pointer to UTF-32 character that is filled with retrieved input

Returns

GATE_RESULT_* result code

write_err()

gate_result_t write_err	(	char const *	buffer,
		gate_size_t	bufferlength,
		gate_size_t *	written )

Writes the contents of the given buffer to the error ouput side of the stream.

Parameters

[in]	buffer	Pointer to buffer thats content is written to error-side of console stream
[in]	bufferlength	Length of buffer in bytes
[out]	written	Pointer to variable the amount of bytes that could be written

Returns

GATE_RESULT_* result code

flush_err()

gate_result_t flush_err

(

)

Flushes the error output side of the stream.

Returns

GATE_RESULT_* result code
