Typedef Documentation

typedef void(* putchar_cb) (char ch)

Function pointer definition for put char callback.

putstr_cb

typedef void(* putstr_cb) (const char *str, int len)

Function pointer definition for put string callback.

Function Documentation

tr_printf()

void tr_printf	(	const char *	fmt,
			... )

Writes the passed in C string to the standard output (stdout).

Parameters

[in]	fmt	C string that contains the text to be written to stdout.
[in]	...	Depends on the format string

tr_printf_init()

void tr_printf_init	(	putchar_cb	putc,
		putstr_cb	puts )

Initializes the printf utility.

Parameters

[in]	putc	Function pointer to a putc function used for writing a single byte.
[in]	puts	Function pointer to a puts function used for writing a string of bytes.

tr_vsprintf()

void tr_vsprintf	(	char *	buf,
		int	maxlen,
		const char *	fmt,
		const va_list	args )

Write formated data from variable argument list to string.

Parameters

[in]	buf	Pointer to a buffer where the resulting C-string is stored. The buffer should be large enough to contain the resulting string.
[in]	maxlen	The max len of the buffer.
[in]	fmt	A printf formatted C string.
[in]	args	A value identifying a variable argument list initialized with va_start().
