afficher des données transmis en streaming

Bonjour

J'ai un programme en C que j'exécute dans une console pour qu'il se connecte à un serveur MMTP normalement certaines données qui ont été transférés d'un serveur sont stockés dans un fichier avec une fonction qui est appelée OutputFile()

le problème c'est que je dois afficher dans ma console ces données au lieu d'afficher les étapes de connexions avec le serveur

le programme qu'il m'on m'a donné est :

Code:

pleaaz help:(

Bonjour,

Si tu veux afficher au fil de l'eau se qui est normalement enregistré dans le fichier, je pense qu'il faut remplacer le fprintf par un printf("%-*s - %s\n", FIELD_SIZE_MSGID, LastMsgIdReceived,DataMsg->Data); (la ligne 609) de la fonction static void ProcessDataMessage(MMTPMsg* Msg).

Bonne continuation.

lorsque j'ai fait la modification dans le fichier original (c àd le premier programme) j'ai reçu une erreur d'autre genre ld.exe cannot find -libpga

j'ai essaié de faire projet/options builder/linker/other linkers et retaper -l libpga

mais une autre erreur qui dit que la fontion : undefined reference to "waitms" ligne 185 et 191 :s :(:(

C'est aussi une erreur de linkage, tu ne dois pas lier la bibliothèque contenant waitms.

Bonjour,

Déjà en premier lieu, as-tu réussie à compiler correctement le programme originale (sans aucune de tes modifications) ?
Comme le dit Bktero, il te manque soit une librairie, soit un module C à ton projet qui contient les sources de la fonction void WaitMs(unsigned long MilliSeconds);

D'après l'un de tes post tu es sous Window7. Est-ce que la macro NT est déclarée ? La fonction WaitMs est déclaré en tant que macro à la ligne 71 #define WaitMs(x) Sleep(x).
Juste pour un essais, essaye de déclarer en haut de ton programme #define NT. Si cette macro (NT) n'est pas déclarée, alors, le compilateur n'inclue pas windows.h et indirectement la fonction Sleep.

Si t'es sous Linux, alors il faut que la macro UNIX soit déclarée et c'est la fonction void WaitMs(unsigned long MilliSeconds) de la ligne 703 qui sera utilisée.

c'était exactement correcte car j'ai défini NT et waitms s'est reconnu finalement :mrgreen::mrgreen:..

Mercii :ccool:

la méthode que Elijha pour l'ffichage du flux reçu s'avère correcte :mrgreen:..mais j'ai enfin de compte constaté que le retour de ce programme(output) qui doit etre le flux reçu du serveur .

Celà parceque je compte le récupérer dans une autre application en Java en utilisant la classe Runtime.:)
