Functions
void	init_subspec (t_subspec *subspec)
	Sets initial values for a s_subspec that are not always set elsewhere.
void	identify_sequence (va_list args, t_sequence *seq)
	Initialize a s_sequence and determine which specifier it needs to handle, and runs the preprocessing function for that specifier. Sets s_sequence::specifier to 0 on failure.
void	parse_subspec (const char **format, t_subspec *subspec, va_list args)
	Parse flags, width, precision, and length.
static int	print (t_sequence seq, int *fd, int total)
	Print appropriate padding characters on either side, as well as the sign / prefix, and call the processing function for the given specifier.
int	handle_sequence (const char **format, va_list args, int *fd, int total)
	Prepares and executes a sequence.

Function Documentation

handle_sequence()

int handle_sequence	(	const char **	format,
		va_list	args,
		int *	fd,
		int	total
	)

Prepares and executes a sequence.

Initializes and parses any subspecifiers, identifies the sequence and executes the preprocessor for it, adds up the final predicted lengths, prints padding, prefixes, and executes the processor for the sequence.

Parameters

[in,out]	format
[in,out]	args
[in,out]	fd
[in]	total

Return values

int	Number of characters printed, or -1 on error.

identify_sequence()

void identify_sequence	(	va_list	args,
