My problème is: i have written a client and a server in C, the client send a char to the server (for example "A") the server increments and send the char "B" to the client etc...

i'd like to:
save the last char received by the client and by the server , for a new connection between them they get the char fom file and continue

is that possible ?

uvszprintf(3alleg4)						  Allegro manual					       uvszprintf(3alleg4)

NAME
uvszprintf - Writes formatted data into a buffer, using size and variable 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 directly, 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? ", "Dave", 25); } RETURN VALUE
Returns the number of characters that would have been written without eventual truncation (like with uvsprintf), not including the termi- nating null character. SEE ALSO
