proc - SerenityOS ProcFS


The kernel can expose process related information in /proc. This functionality is used by various userland programs. All of the output layout (besides symbolic links) in the ProcFS nodes is JSON.

#Consistency and stability of data across multiple read operations

When opening a data node, the kernel generates the required data so it's prepared for read operation when requested to. However, in order to ensure that multiple reads will not create a corrupted data from that data node, a read operation alone will not inquire the kernel to refresh the data. To keep data output being refreshed, the userland has to re-open the data node with a new file descriptor, or to perform the lseek syscall on the open file descriptor to reset the offset to 0.
