Thanks Claudio, but I'm afraid I have another problem. I tried to compile the code that you send but it happened the same error: "parse error before '.' token" at line: first.byte1=0x01; ------------------------------ //struct_test.c typedef struct struct_test { unsigned char byte1; unsigned char byte2; unsigned char byte3; }struct_test; struct_test first, second; first.byte1=0x01; ------------------------------ My real application is trying to implement an UDP client that sends a message to an UDP server. My code is the following and I had the same error compiling it: "parse error before '.' token" at frst variable initialization. ------------------------------------- #include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> #include <arpa/inet.h> #include <netdb.h> #include <stdio.h> #include <stdlib.h> struct sockaddr_in cli, serv; serv.sin_family=AF_INET; serv.sin_addr.s_addr=inet_addr("192.168.200.6"); serv.sin_port=htons(6000); cli.sin_family=AF_INET; cli.sin_addr.s_addr=htonl(192.168.200.241); cli.sin_port=htons(0); --------------------------------------- Please someone have any idea ?
