int int vsprintf ( char buf,
const char fmt,
va_list  args 

vsprintf - Format a string and place it in a buffer : The buffer to place the result into : The format string to use : Arguments for the format string

The function returns the number of characters written into . Use vsnprintf() or vscnprintf() in order to avoid buffer overflows.

If you're not already dealing with a va_list consider using sprintf().

See the vsnprintf() documentation for format string extensions over C99.
