warning: function types not truly compatible in ISO C
Bonjour,
Et encore une !
Voici le prototype de trois fonctions que je trouve dans socket.h :
Code:
1
2
3
4
5
6

11
12

/* This is the type we use for generic socket address arguments.
With GCC 2.7 and later, the funky union causes redeclarations or
uses with any of the listed types to be allowed without complaint.
G++ 2.7 does not support transparent unions so there we want the
old-style declaration, too. */
#if defined __cplusplus || !__GNUC_PREREQ (2, 7) || !defined __USE_GNU

__THROW;
/* Open a connection on socket FD to peer at ADDR (which LEN bytes long).
For connectionless socket types, just set the default address to send to
and the only address from which to accept transmissions.
Return 0 on success, -1 for errors. */
extern int connect (int __fd, __CONST_SOCKADDR_ARG __addr, socklen_t __len)
__THROW;
/* Read N bytes into BUF from socket FD.
Returns the number read or -1 for errors. */
extern ssize_t recv (int __fd, void *__buf, size_t __n, int __flags)
__THROW; |
et voici l'utilisation que j'en fais et qui produit le message d'erreur du titre, le même pour chacune des trois fonctions, incompréhensible :
Code:
1
2
3
4
5
6
7
8
9
10
11
| int bind(int sockfd, const struct sockaddr *my_addr, socklen_t addrlen) {
...
}
int connect(int sockfd, const struct sockaddr *serv_addr, socklen_t addrlen) {
...
}
ssize_t recv(int s, void *buf, size_t len, int flags) {
...
} |
Je ne trouve pas ce qui peut produire cette erreur, tout me semble correct.
Merci pour votre aide.
