Function Documentation

FOURCC make_fourcc (  char *  s  )

make a 32 bit "string-id" Parameters: s  a pointer to 4 chars Returns: the 32 bit "string id" It is not checked whether we really have 4 characters Some compilers understand constants like int id = 'ABCD'; but I could not get it working on the gcc compiler so I had to use this workaround. We can now use id = make_fourcc("ABCD") instead. Definition at line 63 of file riff.cc. References FOURCC.
