android - Access data from proc file within kernel module -

i need access proc files in module on android kernel. need info shown in cat command, cat /proc/uptime. need programmatically.

i tried work proc_fs functions, little fuzzy me, examples create proc file read , it. need use data proc files.

i tred fopen, not seems work on modules.

how can that? i'm newbie on this. i'm working on goldfish android kernel.

thanks.

procfs in-memory file system. interface userspace fetch info , put (config) info kernel data structures. in other words, procfs enables userspace interact , kernel data structures way exist during runtime.

hence, file inside /proc not meant read inside kernel or kernel module. , why 1 want that? in monolithic kernel linux, can access data structures of 1 subsystem in kernel through directly or through pre-defined function.

the following function call might help:

struct timespec uptime;  do_posix_clock_monotonic_gettime(&uptime); 

you can refer /proc/uptime implementation @ link below, seq_file.
