+(use-modules (ice-9 match))

+(match '(+ 1 2)

+  (('+ x y) `(add ,x ,y))

+** New function: scm_c_read (SCM port, void *buffer, scm_sizet size)
+
+Used by an application to read arbitrary number of bytes from a port.
+Same semantics as libc read, except that scm_c_read only returns less
+than SIZE bytes if at end-of-file.
+
+Warning: Doesn't update port line and column counts!
+
+** New function: scm_c_write (SCM port, const void *ptr, scm_sizet size)
+
+Used by an application to write arbitrary number of bytes to an SCM
+port.  Similar semantics as libc write.  However, unlike libc
+write, scm_c_write writes the requested number of bytes and has no
+return value.
+
+Warning: Doesn't update port line and column counts!

 ** New function: scm_init_guile ()
 
 In contrast to scm_boot_guile, scm_init_guile will return normally
