Hello:
Everyone,I want to port WinApi DeviceIoControl to Linux Ioctl.
 
//Windows
USHORT in = COMPRESSION_FORMAT_DEFAULT;
DWORD cbReturned; 
DeviceIoControl(hDevice,FSCTL_SET_COMPRESSION,&in,sizeof(in),NULL,0,&cbReturned,NULL);
 
//Linux
ioctl(hDevice,FSCTL_SET_COMPRESSION,&value)
 
But.I can not find FSCTL_SET_COMPRESSION in my Linux.
 
What is head name of FSCTL_SET_COMPRESSION?

The answer is here:
 
int flags = 0;
ioctl(fd,FS_IOC_GETFLAGS,&flags);
flags |= FS_COMPR_FL;
flags &= ~FS_NOCOMP_FL;
ioctl(fd,FS_IOC_SETFLAGS,&flags);
Thanks!
