Hello, 1) I want to know how much can i write to /proc entry file?? Is there any limitation on file size??? 2)Also how can i call /proc entry files proc_read_myfile function on that file by another kernel module call? What parameters i require to pass and how? Say i have read functions as
struct myfile_data_t { char value[8]; }; struct proc_dir_entry *myfile_file; struct myfile_data_t myfile_data; int proc_read_myfile(char *page, char **start, off_t off, int count, int *eof, void *data) { int len; /* cast the void pointer of data to myfile_data_t*/ struct myfile_data_t *myfile_data=(struct myfile_data_t *)data; /* use sprintf to fill the page array with a string */ len = sprintf(page, "%s", myfile_data->value); return len; } Then can it possible that i can call proc_read_myfile from another kernel module?? Instead read file from user level call? 3) Also Is following code valid of creating /proc files with different file name created by passing function cr_proc(fname)? struct proc_dir_entry *entnew; int cr_proc(char *fname) { if ((entnew1 = create_proc_entry(fname, S_IRUGO | S_IWUSR, NULL)) == NULL) return -EACCES; entnew1->proc_fops = &proc_file_operations; } static struct file_operations proc_file_operations = { open: proc_open, release: proc_release, read: proc_read, write: proc_write, }; What will happen if dynamic file names are going to use same all above 4 functions??? regards, linux_lover __________________________________________________ Do You Yahoo!?
