syntax:

Clib.rvsprintf(formatString, valist)

where:

formatString - string that specifies the final format.

valist - a variable list of arguments to be used according to formatString.

return:

string - specified by formatString on success, else EOF on error.

description:

This method returns formatted output using the variable argument list represented by the parameter valist, a Blob. This method is similar to Clib.sprintf() except that it takes a variable argument list and returns a formatted string based on the arguments, rather than storing it in a string buffer. See Clib.sprintf() and Clib.va_start() for more information. The method Clib.rvsprintf() returns a string specified by formatString on success, else EOF on error.
