Function Documentation

_vscprintf_so()

int _vscprintf_so	(	const char *	format,
		va_list	pargs
	)

compute the size of a string made with format 'fmt' and arguments in the va_list 'ap', helper for vasprintf

Parameters

format	format to pass to printf
pargs	va_list to use as printf parameter

Returns

-1 or the size of the string

asprintf()

int asprintf	(	char *	strp[],
		const char *	fmt,
			...

snprintf from a va_list

Parameters

strp	string holding the result
fmt	format to pass to printf
...	list of format parameters

Returns

Parameters

strp	string holding the result
fmt	format to pass to printf
