vsprintf

int vsprintf(char *s, const char *format,

va_list ap);

The function generates formatted text, under the control of the format format and any

additional arguments, and stores each generated character in successive locations of the array

object whose first element has the address s. The function concludes by storing a null character

in the next location of the array. It returns the number of characters generated -- not including

the null character.

The function accesses additional arguments by using the context information designated by ap.

The program must execute the macro va_start before it calls the function, and then execute

the macro va_end after the function returns.
