/**
* G_MODULE_SUFFIX:
*
* Expands to a shared library suffix for the current platform without the

*
* Deprecated: 2.76: Use g_module_open() instead with @module_name as the
* basename of the file_name argument. You will get the wrong results using
* this macro most of the time:
*
* 1. The suffix on macOS is usually 'dylib', but it's 'so' when using
* Autotools, so there's no way to get the suffix correct using
* a pre-processor macro.
* 2. Prefixes also vary in a platform-specific way. You may or may not have
* a 'lib' prefix for the name on Windows and on Cygwin the prefix is
* 'cyg'.
* 3. The library name itself can vary per platform. For instance, you may
* want to load foo-1.dll on Windows and libfoo.1.dylib on macOS.
*
* g_module_open() takes care of all this by searching the filesystem for
* combinations of possible suffixes and prefixes.

* G_MODULE_EXPORT:
*
* Used to declare functions exported by libraries or modules.

* When compiling for Windows, it marks the symbol as `dllexport`.
*
* When compiling for Linux and Unices, it marks the symbol as having `default`
* visibility. This is no-op unless the code is being compiled with a
* non-default
* [visibility flag](https://gcc.gnu.org/onlinedocs/gcc/Code-Gen-Options.html#index-fvisibility-1260)
* such as `hidden`.
*
* This macro must only be used when compiling a shared module. Modules that
* support both shared and static linking should define their own macro that
* expands to %G_MODULE_EXPORT when compiling the shared module, but is empty
* when compiling the static module on Windows.

*
* 1. If @file_name exists as a regular file, it is used as-is; else
* 2. If @file_name doesn't have the correct suffix and/or prefix for the
* platform, then possible suffixes and prefixes will be added to the
* basename till a file is found and whatever is found will be used; else
* 3. If @file_name doesn't have the ".la"-suffix, ".la" is appended. Either
* way, if a matching .la file exists (and is a libtool archive) the
* libtool archive is parsed to find the actual file name, and that is
* used.
*
* If, at the end of all this, we have a file path that we can access on disk,
* it is opened as a module. If not, @file_name is attempted to be opened as a
* module verbatim in the hopes that the system implementation will somehow be
* able to access it. If that is not possible, %NULL is returned.
*
* Note that this behaviour was different prior to 2.76, but there is some
* overlap in functionality. If backwards compatibility is an issue, kindly
* consult earlier #GModule documentation for the prior search order/behavior
* of @file_name.

* For example, calling g_module_build_path() on a Linux system with a
* @directory of `/lib` and a @module_name of "mylibrary" will return
* `/lib/libmylibrary.so`. On a Windows system, using `\Windows` as the
* directory it will return `\Windows\mylibrary.dll`.
*
* Returns: the complete path of the module, including the standard library
* prefix and suffix. This should be freed when no longer needed
*
* Deprecated: 2.76: Use g_module_open() instead with @module_name as the
* basename of the file_name argument. See %G_MODULE_SUFFIX for why.
