DL.realloc(addr, size) Class Public methods Change the size of the memory allocated at the memory location addr to size bytes. Returns the memory address of the reallocated memory, which may be different than the address passed in.

DL.malloc(size) Class Public methods Allocate size bytes of memory and return the integer memory address for the allocated memory.

DL.free(addr) Class Public methods Free the memory at address addr

fiddle?() Class Public methods Returns true if DL is using Fiddle, the libffi wrapper.

DL.dlwrap(val) Class Public methods Returns a memory pointer of a function's hexadecimal address location val Example: lib = DL.dlopen('/lib64/libc-2.15.so') => #<DL::Handle:0x00000001342460> DL.dlwrap(lib['strcpy'].to_s(16)) => 25522520

DL.dlunwrap(addr) Class Public methods Returns the hexadecimal representation of a memory pointer address addr Example: lib = DL.dlopen('/lib64/libc-2.15.so') => #<DL::Handle:0x00000001342460> lib['strcpy'].to_s(16) => "7f59de6dd240" DL.dlunwrap(DL.dlwrap(lib['strcpy'].to_s(16))) => "7f59de6dd240"

DL.dlopen(so_lib) Class Public methods An interface to the dynamic linking loader This is a shortcut to DL::Handle.new and takes the same arguments. Example: libc_so = "/lib64/libc.so.6" => "/lib64/libc.so.6" libc = DL.dlopen(libc_so) => #<DL::Handle:0x00000000e05b00>
