Function Documentation

char* VMCALL hybuf_write_text	(	struct HyPortLibrary *	portLibrary,
		const char *	buf,
		IDATA	nbytes
	)

Output the buffer onto the another buffer as text.

The in buffer is a UTF8-encoded array of chars. It is converted to the appropriate platform encoding.

Parameters:

[in]	portLibrary	The port library
[in]	buf	buffer of text to be converted.
[in]	nbytes	size of buffer of text to be converted.

Returns:

buffer of converted to the appropriate platform encoding text.

char* VMCALL hyfile_read_text	(	struct HyPortLibrary *	portLibrary,
		IDATA	fd,
		char *	buf,
		IDATA	nbytes
	)

Read a line of text from the file into buf.

Text is converted from the platform file encoding to UTF8. This is mostly equivalent to fgets in standard C.

Parameters:

[in]	portLibrary	The port library
[in]	fd	File descriptor.
[in,out]	buf	Buffer for read in text.
[in]	nbytes	Size of buffer.

Returns:

buf on success, NULL on failure.

IDATA VMCALL hyfile_write_text	(	struct HyPortLibrary *	portLibrary,
		IDATA	fd,
		const char *	buf,
		IDATA	nbytes
	)

Output the buffer onto the stream as text.

The buffer is a UTF8-encoded array of chars. It is converted to the appropriate platform encoding.

Parameters:

[in]	portLibrary	The port library
[in]	fd	the file descriptor.
[in]	buf	buffer of text to be output.
[in]	nbytes	size of buffer of text to be output.

Returns:

0 on success, negative error code on failure.
