Member Function Documentation

unsigned int String::getBytes	(	unsigned char *	buf,
		unsigned int	bufsize,
		unsigned int	index = `0`
	)		const

inherited

read contents of string into a buffer

Parameters

buf	buffer to write data
bufsize	size of buffer in bytes
index	offset to start

Return values

unsigned number of bytes copied, excluding nul terminator

Note: Returned data always nul terminated so buffer size needs to take this into account

bool String::setLength ( unsigned int length )

inherited

set the string length accordingly, expanding if necessary

Parameters

length required for string (nul terminator additional)

Return values

true	on success, false on failure

Note: extra characters are undefined

Member Data Documentation

const String String::empty

staticinherited

An empty string evaluates to true.

const String String::nullstr

staticinherited

A null string evaluates to false.
