The Escape library is a library that acts implements some of the missing function from the PS3 GameOS system that are needed for the proper functioning of the EFL.
Escape is a library your application links to. The procedure for this is very simple. You simply have to compile your application with the appropriate compiler flags that the
pkg-config script outputs. For example:
Compiling C or C++ files into object files:
gcc -c -o main.o main.c `pkg-config --cflags escape`
Linking object files into a binary executable:
gcc -o my_application main.o `pkg-config --libs escape`
After you understood what Escape is and installed it in your system you should proceed understanding the programming interface.
