vsprintf — Format a string and place it in a buffer
int vsprintf ( | char * buf, |
| const char * fmt, | |
va_list args); |
bufThe buffer to place the result into
fmtThe format string to use
argsArguments for the format string
The function returns the number of characters written
into buf. Use vsnprintf or vscnprintf in order to avoid
buffer overflows.
Call this function if you are already dealing with a va_list.
You probably want sprintf instead.
See the vsnprintf documentation for format string extensions over C99.
