SceLibKernel

SceLibKernel, not to be confused with Kernel is a user module that implements wrappers to some common syscalls (for example, SceIofilemgr), some usermode standard library functions (including C standard library), and other common features like heap management. This module is the functionality similar to libc.so.6 on Linux.
