When writing a driver for a character device,
static struct file_operations will be used.

Well,,,what's the definition of file_operation in Linux?

Or how to find out its definition in Linux source directory?
 

file_operation structure is data type which contains the fuction pointers as the members. The function pointers correspods to the various operations supported by the device driver you are writing.
