patterns to the yield function for a loop body.

The state values are:

abi.RF_PANIC = 2     // body of loop is either currently running, or has panicked

Not all Go types can be mapped to C types in a useful way.
Go struct types are not supported; use a C struct type.
Go array types are not supported; use a C pointer.

Go functions that take arguments of type string may be called with the
C type _GoString_, described above. The _GoString_ type will be
automatically defined in the preamble. Note that there is no way for C
