set_close_on

函数名称：We only lock f_pos if we have threads or if the file might be* shared with another process. In both cases we'll have an elevated* file count (done either by fdget() or by fork()).

函数原型：void set_close_on_exec(unsigned int fd, int flag)

返回类型：void

参数：

类型	参数	名称
unsigned int	fd
int	flag

820

files等于files

822

加自旋锁

823

fdt等于files_fdtable(files)

824

如果flag则__set_close_on_exec(fd, fdt)

826

否则__clear_close_on_exec(fd, fdt)

828
