* Changes to Scheme functions and syntax
+** Escape procedures created by call-with-current-continuation now
+accept any number of arguments, as required by R5RS.
+
** New function `make-object-property'
This function returns a new `procedure with setter' P that can be used
** Deprecated: scm_sloppy_memq, scm_sloppy_memv, scm_sloppy_member
-Instead, use scm_memq, scm_memv, scm_member.
+Instead, use scm_c_memq or scm_memq, scm_memv, scm_member.
+
+** New function: port? X
+
+Returns a boolean indicating whether X is a port. Equivalent to
+`(or (input-port? X) (output-port? X))'.
+
+** New function: port-for-each proc
+
+Apply PROC to each port in the Guile port table in turn. The
+return value is unspecified.
+
+** New function: dup2 oldfd newfd
+
+A simple wrapper for the `dup2' system call. Copies the file
+descriptor OLDFD to descriptor number NEWFD, replacing the
+previous meaning of NEWFD. Both OLDFD and NEWFD must be integers.
+Unlike for dup->fdes or primitive-move->fdes, no attempt is made
+to move away ports which are using NEWFD\n". The return value is
+unspecified.
+
+** New function: close-fdes fd
+
+A simple wrapper for the `close' system call. Close file
+descriptor FD, which must be an integer. Unlike close (*note
+close: Ports and File Descriptors.), the file descriptor will be
+closed even if a port is using it. The return value is
+unspecified.
+
+** Deprecated: close-all-ports-except. This was intended for closing
+ports in a child process after a fork, but it has the undesirable side
+effect of flushing buffers. port-for-each is more flexible.
+
+** The (ice-9 popen) module now attempts to set up file descriptors in
+the child process from the current Scheme ports, instead of using the
+current values of file descriptors 0, 1, and 2 in the parent process.
+
+** Removed function: builtin-weak-bindings
+
+There is no such concept as a weak binding any more.
* Changes to the gh_ interface
In contrast to scm_boot_guile, scm_init_guile will return normally
after initializing Guile. It is not available on all systems, tho.
+** New functions: scm_str2symbol, scm_mem2symbol
+
+The function scm_str2symbol takes a const char* pointing to a zero-terminated
+field of characters and creates a scheme symbol object from that C string.
+The function scm_mem2symbol takes a const char* and a number of characters and
+creates a symbol from the characters in that memory area.
+
** New functions: scm_primitive_make_property
scm_primitive_property_ref
scm_primitive_property_set_x
calling scm_done_malloc with negative argument, was somewhat
unintuitive (and is still available, of course).
+** New function: scm_c_memq (SCM obj, SCM list)
+
+This function provides a fast C level alternative for scm_memq for the case
+that the list parameter is known to be a proper list. The function is a
+replacement for scm_sloppy_memq, but is stricter in its requirements on its
+list input parameter, since for anything else but a proper list the function's
+behaviour is undefined - it may even crash or loop endlessly. Further, for
+the case that the object is not found in the list, scm_c_memq returns #f which
+is similar to scm_memq, but different from scm_sloppy_memq's behaviour.
+
** New global variable scm_gc_running_p introduced.
Use this variable to find out if garbage collection is being executed. Up to
may change. Further, scm_gc_heap_lock is not set throughout gc, thus the use
of this variable is (and has been) not fully safe anyway.
+** New macros: SCM_BITVECTOR_MAX_LENGTH, SCM_UVECTOR_MAX_LENGTH
+
+Use these instead of SCM_LENGTH_MAX.
+
** New macros: SCM_CONTINUATION_LENGTH, SCM_CCLO_LENGTH, SCM_STACK_LENGTH,
SCM_STRING_LENGTH, SCM_SYMBOL_LENGTH, SCM_UVECTOR_LENGTH,
SCM_BITVECTOR_LENGTH, SCM_VECTOR_LENGTH.
Use these instead of SCM_LENGTH.
+** New macros: SCM_SET_CONTINUATION_LENGTH, SCM_SET_STRING_LENGTH,
+SCM_SET_SYMBOL_LENGTH, SCM_SET_VECTOR_LENGTH, SCM_SET_UVECTOR_LENGTH,
+SCM_SET_BITVECTOR_LENGTH
+
+Use these instead of SCM_SETLENGTH
+
** New macros: SCM_STRING_CHARS, SCM_SYMBOL_CHARS, SCM_CCLO_BASE,
SCM_VECTOR_BASE, SCM_UVECTOR_BASE, SCM_BITVECTOR_BASE, SCM_COMPLEX_MEM,
SCM_ARRAY_MEM
-Use these instead of SCM_CHARS or SCM_VELTS.
+Use these instead of SCM_CHARS, SCM_UCHARS, SCM_ROCHARS, SCM_ROUCHARS or
+SCM_VELTS.
+
+** New macros: SCM_SET_BIGNUM_BASE, SCM_SET_STRING_CHARS,
+SCM_SET_SYMBOL_CHARS, SCM_SET_UVECTOR_BASE, SCM_SET_BITVECTOR_BASE,
+SCM_SET_VECTOR_BASE
+
+Use these instead of SCM_SETCHARS.
** New macro: SCM_BITVECTOR_P
SCM_VALIDATE_STRINGORSUBSTR, SCM_FREEP, SCM_NFREEP, SCM_CHARS, SCM_UCHARS,
SCM_VALIDATE_ROSTRING, SCM_VALIDATE_ROSTRING_COPY,
SCM_VALIDATE_NULLORROSTRING_COPY, SCM_ROLENGTH, SCM_LENGTH, SCM_HUGE_LENGTH,
-SCM_SUBSTRP, SCM_SUBSTR_STR, SCM_SUBSTR_OFFSET, SCM_COERCE_SUBSTR
+SCM_SUBSTRP, SCM_SUBSTR_STR, SCM_SUBSTR_OFFSET, SCM_COERCE_SUBSTR,
+SCM_ROSTRINGP, SCM_RWSTRINGP, SCM_VALIDATE_RWSTRING, SCM_ROCHARS,
+SCM_ROUCHARS, SCM_SETLENGTH, SCM_SETCHARS, SCM_LENGTH_MAX, SCM_GC8MARKP,
+SCM_SETGC8MARK, SCM_CLRGC8MARK, SCM_GCTYP16, SCM_GCCDR
Use SCM_ASSERT_RANGE or SCM_VALIDATE_XXX_RANGE instead of SCM_OUTOFRANGE.
Use scm_memory_error instead of SCM_NALLOC.
Use a type specific accessor instead of SCM(_|_RO|_HUGE_)LENGTH.
Use SCM_VALIDATE_(SYMBOL|STRING) instead of SCM_VALIDATE_ROSTRING.
Use SCM_STRING_COERCE_0TERMINATION_X instead of SCM_COERCE_SUBSTR.
+Use SCM_STRINGP or SCM_SYMBOLP instead of SCM_ROSTRINGP.
+Use SCM_STRINGP instead of SCM_RWSTRINGP.
+Use SCM_VALIDATE_STRING instead of SCM_VALIDATE_RWSTRING.
+Use SCM_STRING_CHARS instead of SCM_ROCHARS.
+Use SCM_STRING_UCHARS instead of SCM_ROUCHARS.
+Use a type specific setter macro instead of SCM_SETLENGTH.
+Use a type specific setter macro instead of SCM_SETCHARS.
+Use a type specific length macro instead of SCM_LENGTH_MAX.
+Use SCM_GCMARKP instead of SCM_GC8MARKP.
+Use SCM_SETGCMARK instead of SCM_SETGC8MARK.
+Use SCM_CLRGCMARK instead of SCM_CLRGC8MARK.
+Use SCM_TYP16 instead of SCM_GCTYP16.
+Use SCM_CDR instead of SCM_GCCDR.
** Removed function: scm_struct_init
+** Removed variable: scm_symhash_dim
+
+** Renamed function: scm_make_cont has been replaced by
+scm_make_continuation, which has a different interface.
+
** Deprecated function: scm_call_catching_errors
Use scm_catch or scm_lazy_catch from throw.[ch] instead.
There is now only a single symbol type scm_tc7_symbol.
The tag scm_tc7_lvector was not used anyway.
+** Deprecated function: scm_make_smob_type_mfpe, scm_set_smob_mfpe.
+
+Use scm_make_smob_type and scm_set_smob_XXX instead.
+
+** New function scm_set_smob_apply.
+
+This can be used to set an apply function to a smob type.
