osal_fileops_ 的协作图:

成员变量
int(*	open )(void *private_data)
int(*	read )(char *buf, int size, long *offset, void *private_data)
int(*	write )(const char *buf, int size, long *offset, void *private_data)
long(*	llseek )(long offset, int whence, void *private_data)
int(*	release )(void *private_data)
unsigned int(*	poll )(osal_poll *osal_poll, void *private_data)
int(*	mmap )(osal_vm *vm, unsigned long start, unsigned long end, unsigned long vm_pgoff, void *private_data)
int(*	fasync )(int fd, void *filp, int mode)
osal_ioctl_cmd *	cmd_list
unsigned int	cmd_cnt

结构体成员变量说明

cmd_cnt

unsigned int osal_fileops_::cmd_cnt

cmd_list

osal_ioctl_cmd* osal_fileops_::cmd_list

fasync

int(* osal_fileops_::fasync) (int fd, void *filp, int mode)

llseek

long(* osal_fileops_::llseek) (long offset, int whence, void *private_data)

mmap

int(* osal_fileops_::mmap) (osal_vm *vm, unsigned long start, unsigned long end, unsigned long vm_pgoff, void *private_data)

open

int(* osal_fileops_::open) (void *private_data)

poll

unsigned int(* osal_fileops_::poll) (osal_poll *osal_poll, void *private_data)

read

int(* osal_fileops_::read) (char *buf, int size, long *offset, void *private_data)

release

int(* osal_fileops_::release) (void *private_data)

write

int(* osal_fileops_::write) (const char *buf, int size, long *offset, void *private_data)
