uvszprintf(3) Allegro manual uvszprintf(3) NAME uvszprintf - Writes formatted data into a buffer, using size and vari- able arguments. Allegro game programming library. SYNOPSIS #include <allegro.h> int uvszprintf(char *buf, int size, const char *format, va_list args); DESCRIPTION This is like uszprintf(), but you pass the variable argument list di- rectly, instead of the arguments themselves. Example: #include <stdarg.h> void log_message(const char *format, ...) { char buffer[100]; va_list parameters; va_start(parameters, format); uvszprintf(buffer, sizeof(buffer), format, parameters); va_end(parameters); append_buffer_to_logfile(log_name, buffer); send_buffer_to_other_networked_players(multicast_ip, buffer); and_also_print_it_on_the_screen(cool_font, buffer); } void some_other_function(void) { log_message("Hello %s, are you %d years old?\n", "Dave", 25); } RETURN VALUE Returns the number of characters that would have been written without eventual truncation (like with uvsprintf), not including the terminat- ing null character.
