/*
 * ------------------------------
 * Compile time directives
 * ------------------------------
 * For most purposes, PH7 can be built just fine using the default compilation options.
 * However, if required, the compile-time options documented below can be used to omit
 * PH7 features (resulting in a smaller compiled library size) or to change the default
 * values of some parameters. 
 * Every effort has been made to ensure that the various combinations of compilation 
 * options work harmoniously and produce a working library.
 *
 * PH7_ENABLE_THREADS
 *   This option controls whether or not code is included in PH7 to enable it to operate
 *   safely in a multithreaded environment. The default is not. That is,all mutexing code
 *   is omitted and it is unsafe to use PH7 in a multithreaded program. When compiled
 *   with the PH7_ENABLE_THREADS directive enabled, PH7 can be used in a multithreaded
 *   program and it's safe to share the same virtual machine and engine instance between
 *   two or more threads.
 *   The value of PH7_ENABLE_THREADS can be determined at run-time using the
 *   ph7_lib_is_threadsafe() interface.When PH7 has been compiled with PH7_ENABLE_THREAD
 *   then the threading mode can be altered at run-time using the ph7_lib_config()
 *   interface together with one of these verbs:
 *      PH7_LIB_CONFIG_THREAD_LEVEL_SINGLE
 *      PH7_LIB_CONFIG_THREAD_LEVEL_MULTI
 *   Also note,platforms others than Windows and UNIX systems must install their own
 *   mutex subsystem via  ph7_lib_config() with a configuration verb set to
 *   PH7_LIB_CONFIG_USER_MUTEX. Otherwise the library is not threadsafe.
 *   Note that you must link PH7 with the POSIX threads library under UNIX-like systems
 *   (i.e: -lpthread).Otherwise you will get a link time error.
 * Options To Omit/Enable Features:
 *   The following options can be used to reduce the size of the compiled library
 *   by omitting optional features. This is probably only useful in embedded systems
 *   where space is especially tight, as even with all features included the PH7 library
 *   is relatively small. Don't forget to tell your compiler to optimize for binary
 *   size! (the -Os option if using GCC).
 *   Telling your compiler to optimize for size usually has a much larger impact
 *   on library footprint than employing any of these compile-time options.
 *   PH7_DISABLE_BUILTIN_FUNC
 *     PH7 come with more than 460 built-in functions suitable for most purposes ranging
 *     from string/XML/INI processing to ZIP extracting, Base64 encoding/decoding and so on.
 *     If this directive is enabled, all the built-in functions are omitted from the build.
 *     Note that language construct functions such as is_int(), is_string(), func_get_arg(),
 *     define(), etc. are not omitted from the build and are not affected by this directive.
 *   PH7_ENABLE_MATH_FUNC
 *     If this directive is enabled, built-in math functions such as sqrt(),abs(),
 *     log(), ceil(), etc. are included in the build. Note that you may need to link
 *     PH7 with the math library in same linux/BSD flavor (i.e: -lm).Otherwise you
 *     will get a link time error.
 *  PH7_DISABLE_DISK_IO
 *     If this directive is enabled, built-in Virtual File System functions such as
 *     chdir(), mkdir(), chroot(), unlink(), delete(), etc. are omitted from the build.
 *  PH7_DISABLE_HASH_IO
 *     If this directive is enabled, built-in hash functions such as md5(), sha1(),
 *     md5_file(), crc32(), etc. are omitted from the build.
 *  PH7_OMIT_FLOATING_POINT
 *     This option is used to omit floating-point number support from the PH7 library
 *     if compiling for a processor that lacks floating point support. When specified
 *     the library will substitute 64-bit integer arithmetic for floating-point which
 *     mean that 25.e-3 and 25 are equals and are of type integer.

 * An instance of the ph7_vfs object defines the interface between the PH7 core
 * and the underlying operating system. The "vfs" in the name of the object stands
 * for "virtual file system". The vfs is used to implement PHP system functions
 * such as mkdir(), chdir(), stat(), get_user_name() and many more.
 * The value of the iVersion field is initially 2 but may be larger in future versions
 * of PH7.
 * Additional fields may be appended to this object when the iVersion value is increased.
 * Only a single vfs can be registered within the PH7 core. Vfs registration is done
 * using the ph7_lib_config() interface with a configuration verb set to PH7_LIB_CONFIG_VFS.
 * Note that Windows and UNIX (Linux, FreeBSD, Solaris, Mac OS X, etc.) users does not have to
 * worry about registering and installing a vfs since PH7 come with a built-in vfs for these
 * platforms which implement most the methods defined below.
 * Host-application running on exotic systems (ie: Other than Windows and UNIX systems) must
 * register their own vfs in order to be able to use and call PHP system function.
 * Also note that the ph7_compile_file() interface depend on the xMmap() method of the underlying
 * vfs which mean that this method must be available (Always the case using the built-in VFS)
 * in order to use this interface.
 * Developers wishing to implement the vfs methods can contact symisc systems to obtain
 * the PH7 VFS C/C++ Specification manual.

/*
 * PH7 IO Stream Device.
 *
 * An instance of the ph7_io_stream object defines the interface between the PH7 core
 * and the underlying stream device.
 * A stream is a smart mechanism for generalizing file, network, data compression
 * and other IO operations which share a common set of functions using an abstracted
 * unified interface.
 * A stream device is additional code which tells the stream how to handle specific
 * protocols/encodings. For example, the http device knows how to translate a URL
 * into an HTTP/1.1 request for a file on a remote server.
 * PH7 come with two built-in IO streams device:
 * The file:// stream which perform very efficient disk IO and the php:// stream
 * which is a special stream that allow access various I/O streams (See the PHP official
 * documentation for more information on this stream).
 * A stream is referenced as: scheme://target 
 * scheme(string) - The name of the wrapper to be used. Examples include: file,http,https,ftp,
 * ftps, compress.zlib, compress.bz2, and php. If no wrapper is specified,the function default
 * is used (typically file://). 
 * target - Depends on the device used. For filesystem related streams this is typically a path
 * and filename of the desired file.For network related streams this is typically a hostname,often
 * with a path appended. 
 * IO stream devices are registered using a call to ph7_vm_config() with a configuration verb
 * set to PH7_VM_CONFIG_IO_STREAM.
 * Currently the PH7 development team is working on the implementation of the http:// and ftp://
 * IO stream protocols. These devices will be available in the next major release of the PH7 engine.
 * Developers wishing to implement their own IO stream devices must understand and follow
 * The PH7 IO Stream C/C++ specification manual (http://ph7.symisc.net/io_stream_spec.html).
