int
streambuf::vform (const
char * format, va_list args)
Method
Similar to vfprintf
(file,
format,
args).
The format
is a printf-style
format control string, which is used to format the argument list args,
printing the result on the this
streambuf. The result is the number of characters printed. See also vprintf,
vfprintf,
vsprintf.
int
streambuf::scan (const
char * format, ...)
Method
Similar to fscanf
(file, format, ...).
The format
is a scanf-style
format control string, which is used to read the (variable number of) arguments
from the this
streambuf. The result is the number of items assigned, or EOF
in case of input failure before any conversion. See also scanf,
fscanf,
sscanf.
int
streambuf::vscan (const
char * format, va_list args)
Method
Like streambuf::scan,
but takes a single va_list
argument.
