putc()

void putc

(

char

c

)

Prints a char, using vput(char c); Replaces '' with "\b \b".

Parameters

(

char

c

)

Prints a char though the standard streams.

Parameters

c	The charecter to be printed.

vsnprintf()

int vsnprintf	(	char *	buf,
		size_t	size,
		const char *	fmt,
		va_list	args )

Formats a string into a buffer using a va_list.

Parameters

buf	destination buffer.
size	buffer size in bytes.
fmt	format string.
args	variable argument list.

Returns

number of characters written (excluding null terminator).

warn()
