When I compile and run the following example code within cygwin (gcc
msgsnd.c -o msgsnd), I get an error "Bad system call"
This seems to be a bug; it runs fine under linux.
#include <sys/msg.h>
int main() {
int msqid = 0;
int rc;
size_t msgsz;
struct {
long int mtype;
char mtext[256];
} mymsg;
msgsz = 256;
mymsg.mtype = 1;
rc = msgsnd(msqid, &mymsg, msgsz, IPC_NOWAIT);
return 0;
}
