我使用fcntl的F_SETLKW获取读锁,然后尝试使用fcntl的F_GETLK从同一进程读取相同的锁。但是结果是不合适的。以下是示例代码 #include<stdio.h>#include<string.h>#include<fcntl.h>#include<unistd.h>intmain(int argc,char**argv){int fd;struct flock fl;if((fd=open("lockfile",O_RDWR))==-1){perror(...
> F_GETFD > F_SETFD > F_GETFL > F_SETFL > F_GETOWN > F_SETOWN > FD_CLOEXEC > > Neighter F_GETLK nor F_SETLK is there. Am I missing something? Yes, Guile seems to be missing those. These are just numbers, so you can probably just: (define F_GETLK 5) (define F_SETLK 6)...
