Function Documentation

vasprintf()

int vasprintf	(	char **	out,
		const char *	fmt,
		va_list	ap
	)

Prints a formatted string to a newly allocated string.

This function is a helper around vxprintf, which will print to a string, and otherwise behaves the same as normal glibc (v)asprintf. The string will be allocated using psyqo_malloc(), and must be freed using psyqo_free().

Parameters

out	The pointer to the string to allocate.
fmt	The format string.
ap	The vararg list of arguments.

Returns

int The number of bytes written.

vsnprintf()

int vsnprintf	(	char *	buf,
		size_t	n,
		const char *	fmt,
		va_list	ap
	)

Prints a formatted string to a length-limited string.

This function is a helper around vxprintf, which will print to a string, and otherwise behaves the same as normal libc (v)snprintf.

Parameters

buf	The buffer to print to.
n	The maximum number of bytes to write, including the terminating null byte.
fmt	The format string.
ap	The vararg list of arguments.

Returns

int The number of bytes written.

vsprintf()

int vsprintf	(	char *	buf,
		const char *	fmt,
		va_list	ap
	)

Prints a formatted string to a string.

This function is a helper around vxprintf, which will print to a string, and otherwise behaves the same as normal libc (v)sprintf.

Parameters

buf	The buffer to print to.
fmt	The format string.
ap	The vararg list of arguments.

Returns

int The number of bytes written.

vxprintf()

int vxprintf	(	void *	func,
		void *	arg,
		const char *	format,
		va_list	ap
	)
