libpkgconf `client` module
==========================
The libpkgconf `client` module implements the `pkgconf_client_t` "client" object.
Client objects store all necessary state for libpkgconf allowing for multiple instances to run
in parallel.
Client objects are not thread safe, in other words, a client object should not be shared across
thread boundaries.
.. c:function:: void pkgconf_client_init(pkgconf_client_t *client, pkgconf_error_handler_func_t error_handler)
Initialise a pkgconf client object.
:param pkgconf_client_t* client: The client to initialise.
:param pkgconf_error_handler_func_t error_handler: An optional error handler to use for logging errors.
:param void* error_handler_data: user data passed to optional error handler
:return: nothing
.. c:function:: pkgconf_client_t* pkgconf_client_new(pkgconf_error_handler_func_t error_handler)
Allocate and initialise a pkgconf client object.
:param pkgconf_error_handler_func_t error_handler: An optional error handler to use for logging errors.
:param void* error_handler_data: user data passed to optional error handler
:return: A pkgconf client object.
:rtype: pkgconf_client_t*
.. c:function:: void pkgconf_client_deinit(pkgconf_client_t *client)
Release resources belonging to a pkgconf client object.
:param pkgconf_client_t* client: The client to deinitialise.
:return: nothing
.. c:function:: void pkgconf_client_free(pkgconf_client_t *client)
Release resources belonging to a pkgconf client object and then free the client object itself.
:param pkgconf_client_t* client: The client to deinitialise and free.
:return: nothing
.. c:function:: const char *pkgconf_client_get_sysroot_dir(const pkgconf_client_t *client)
Retrieves the client's sysroot directory (if any).
:param pkgconf_client_t* client: The client object being accessed.
:return: A string containing the sysroot directory or NULL.
:rtype: const char *
.. c:function:: void pkgconf_client_set_sysroot_dir(pkgconf_client_t *client, const char *sysroot_dir)
Sets or clears the sysroot directory on a client object. Any previous sysroot directory setting is
automatically released if one was previously set.
Additionally, the global tuple ``$(pc_sysrootdir)`` is set as appropriate based on the new setting.
:param pkgconf_client_t* client: The client object being modified.
:param char* sysroot_dir: The sysroot directory to set or NULL to unset.
:return: nothing
.. c:function:: const char *pkgconf_client_get_buildroot_dir(const pkgconf_client_t *client)
Retrieves the client's buildroot directory (if any).
:param pkgconf_client_t* client: The client object being accessed.
:return: A string containing the buildroot directory or NULL.
:rtype: const char *
.. c:function:: void pkgconf_client_set_buildroot_dir(pkgconf_client_t *client, const char *buildroot_dir)
Sets or clears the buildroot directory on a client object. Any previous buildroot directory setting is
automatically released if one was previously set.
Additionally, the global tuple ``$(pc_top_builddir)`` is set as appropriate based on the new setting.
:param pkgconf_client_t* client: The client object being modified.
:param char* buildroot_dir: The buildroot directory to set or NULL to unset.
:return: nothing
