Detailed Description

Lightweight printf with float support header.

Function Documentation

int vex_printf	(	const char *	format,
			...
	)

send formated string to the console

Parameters

[in]

format

The format string

Returns

the number of characters that were output

This has similar but reduced functionality to the standard library function sprintf

int vex_chprintf	(	vexStream *	chp,
		const char *	format,
			...
	)

send formated string to a vexStream

Parameters

[in]	chp	The stream
[in]	format	The format string

Returns

the number of characters that were output

This function is used as a direct replacement for chprintf. It has similar but reduced functionality to the standard library function sprintf.

int vex_vprintf	(	const char *	format,
		va_list	args
	)

send formated string to a vexStream

Parameters

[in]	format	The format string
[in]	args	variable argument list

Returns

the number of characters that were output

This has similar but reduced functionality to the standard library function sprintf. This version takes a variable argument list directly.

int vex_vchprintf	(	vexStream *	chp,
		const char *	format,
		va_list	args
	)

send formated string to a vexStream

Parameters

[in]	chp	The stream
[in]	format	The format string
[in]	args	variable argument list

Returns

the number of characters that were output

This has similar but reduced functionality to the standard library function sprintf. This version takes a variable argument list directly and can also output to a stream that is not the CONSOLE.

int vex_sprintf	(	char *	out,
		const char *	format,
			...
	)

create formated string in a buffer

Parameters

[out]	out	The output buffer
[in]	format	The format string

Returns

the number of characters that were output

This has similar but reduced functionality to the standard library function sprintf

int vex_snprintf	(	char *	out,
		uint16_t	max_len,
		const char *	format,
			...
	)

create formated string in a buffer

Parameters

[out]	out	The output buffer
[out]	max_len	The output buffer length
[in]	format	The format string

Returns

the number of characters that were output

This has similar but reduced functionality to the standard library function sprintf

int vex_vsprintf	(	char *	out,
		const char *	format,
		va_list	args
	)

create formated string in a buffer from a va_list

Parameters

[out]	out	The output buffer
[in]	format	The format string
[in]	args	a variable argument list

Returns

the number of characters that were output

This has similar but reduced functionality to the standard library function sprintf

int vex_vsnprintf	(	char *	out,
		uint16_t	max_len,
		const char *	format,
		va_list	args
	)

create formated string in a buffer from a va_list

Parameters

[out]	out	The output buffer
[out]	max_len	The output buffer length
[in]	format	The format string
[in]	args	a variable argument list

Returns

the number of characters that were output

This has similar but reduced functionality to the standard library function sprintf
