sprintf — printf-style formatted output to a string variable.
sprintf write printf-style formatted output to a string variable, similarly to the C function sprintf(). sprintf runs at i-time only.
Sfmt -- format string, has the same format as in printf() and other similar C functions, except length modifiers (l, ll, h, etc.) are not supported. The following conversion specifiers are allowed:
d, i, o, u, x, X, e, E, f, F, g, G, c, s
xarg1, xarg2, ... -- input arguments (max. 30) for format, should be i-rate for all conversion specifiers except %s, which requires a string argument. Integer formats like %d round the input values to the nearest integer.
Here is an example of the sprintf opcode. It uses the file sprintf.csd.

See the sections Real-time Audio and Command Line Flags for more information on using command line flags.

Its output should include lines like this:
