Hi;I am looking for 'proc fs' type of solution in User space.In Linux Kernel space, we can register read/write function for a proc file and those got called while doing respective operation on that file.Is there same kind of mechansim availabel in C library for user space. Can we crate a file and register read/write callback functions for that file in User space application?So that when "cat " is exectued, the read callback function of that file for called.Please let know if there any mechansim exist for this in User space.Thanks in advance.
