vscnprintf — Format a string and place it in a buffer
int vscnprintf ( | char * buf, |
| size_t size, | |
| const char * fmt, | |
va_list args); |
bufThe buffer to place the result into
sizeThe size of the buffer, including the trailing null space
fmtThe format string to use
argsArguments for the format string
The return value is the number of characters which have been written into
the buf not including the trailing '\0'. If size is <= 0 the function
returns 0.
Call this function if you are already dealing with a va_list.
You probably want scnprintf instead.
See the vsnprintf documentation for format string extensions over C99.
