* ------------------------------
* 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.

* PH7 Virtual File System (VFS).

* 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).
