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
|
|
|
|
.. c:function:: bool pkgconf_error(const pkgconf_client_t *client, const char *format, ...)
|
|
|
|
Report an error to a client-registered error handler.
|
|
|
|
:param pkgconf_client_t* client: The pkgconf client object to report the error to.
|
|
:param char* format: A printf-style format string to use for formatting the error message.
|
|
:return: true if the error handler processed the message, else false.
|
|
:rtype: bool
|
|
|
|
.. c:function:: bool pkgconf_default_error_handler(const char *msg, const pkgconf_client_t *client, const void *data)

|
|
|
The default pkgconf error handler.
|
|
|
|
:param char* msg: The error message to handle.
|
|
:param pkgconf_client_t* client: The client object the error originated from.
|
|
:param void* data: An opaque pointer to extra data associated with the client for error handling.
|
|
:return: true (the function does nothing to process the message)
|
|
:rtype: bool
|
|
|
|
.. c:function:: unsigned int pkgconf_client_get_flags(const pkgconf_client_t *client)
|
|
|
|
Retrieves resolver-specific flags associated with a client object.
|
|
|
|
:param pkgconf_client_t* client: The client object to retrieve the resolver-specific flags from.
|
|
:return: a bitfield of resolver-specific flags
|
|
:rtype: uint
|
|
|
|
.. c:function:: void pkgconf_client_set_flags(pkgconf_client_t *client, unsigned int flags)
|
|
|
|
Sets resolver-specific flags associated with a client object.
|
|
|

|
.. c:function:: const char *pkgconf_client_get_prefix_varname(const pkgconf_client_t *client)
|
|
|
|
Retrieves the name of the variable that should contain a module's prefix.
|
|
In some cases, it is necessary to override this variable to allow proper path relocation.
|
|
|
|
:param pkgconf_client_t* client: The client object to retrieve the prefix variable name from.
|
|
:return: the prefix variable name as a string
|
|

|
|
|
|
Sets the name of the variable that should contain a module's prefix.
|

|
|
|
|
:param pkgconf_client_t* client: The client object to set the prefix variable name on.
|
|
:param char* prefix_varname: The prefix variable name to set.
