libpkgconf `dependency` module
|
|
==============================
|
|
|
|
The `dependency` module provides support for building `dependency lists` (the basic component of the overall `dependency graph`) and
|
|
`dependency nodes` which store dependency information.
|
|
|
|
.. c:function:: pkgconf_dependency_t *pkgconf_dependency_add(pkgconf_list_t *list, const char *package, const char *version, pkgconf_pkg_comparator_t compare)
|
|
|
|
Adds a parsed dependency to a dependency list as a dependency node.
|
|
|
|
:param pkgconf_client_t* client: The client object that owns the package this dependency list belongs to.
|
|
:param pkgconf_list_t* list: The dependency list to add a dependency node to.
|
|
:param char* package: The package `atom` to set on the dependency node.
|
|
:param char* version: The package `version` to set on the dependency node.
|
|
:param pkgconf_pkg_comparator_t compare: The comparison operator to set on the dependency node.
|
|
:param uint flags: Any flags to attach to the dependency node.
|
|
:return: A dependency node.
|
|
:rtype: pkgconf_dependency_t *
|
|
|
|
.. c:function:: void pkgconf_dependency_append(pkgconf_list_t *list, pkgconf_dependency_t *tail)
|
|
|
|
Adds a dependency node to a pre-existing dependency list.
|
|
|
|
:param pkgconf_list_t* list: The dependency list to add a dependency node to.
|
|
:param pkgconf_dependency_t* tail: The dependency node to add to the tail of the dependency list.
|
|
:return: nothing
|
|
|
|
.. c:function:: void pkgconf_dependency_free_one(pkgconf_dependency_t *dep)
|
|
|
|
Frees a dependency node.
|
|
|
|
:param pkgconf_dependency_t* dep: The dependency node to free.
|
|
:return: nothing
|
|
|
|
.. c:function:: pkgconf_dependency_t *pkgconf_dependency_ref(pkgconf_client_t *owner, pkgconf_dependency_t *dep)
|
|
|
|
Increases a dependency node's refcount.
|
|
|
|
:param pkgconf_client_t* owner: The client object which owns the memory of this dependency node.
|
|
:param pkgconf_dependency_t* dep: The dependency to increase the refcount of.
|
|
:return: the dependency node on success, else NULL
|
|
|
|
.. c:function:: void pkgconf_dependency_unref(pkgconf_client_t *owner, pkgconf_dependency_t *dep)
|
|
|
|
Decreases a dependency node's refcount and frees it if necessary.
|
|
|
|
:param pkgconf_client_t* owner: The client object which owns the memory of this dependency node.
|
|
:param pkgconf_dependency_t* dep: The dependency to decrease the refcount of.
|
|
:return: nothing
|
|
|
|
.. c:function:: void pkgconf_dependency_free(pkgconf_list_t *list)
|
|
|
|
Release a dependency list and it's child dependency nodes.
|
|
|
|
:param pkgconf_list_t* list: The dependency list to release.
|
|
:return: nothing
|
|
|
|
.. c:function:: void pkgconf_dependency_parse_str(pkgconf_list_t *deplist_head, const char *depends)
|
|
|
|
Parse a dependency declaration into a dependency list.
|
|
Commas are counted as whitespace to allow for constructs such as ``@SUBSTVAR@, zlib`` being processed
|
|
into ``, zlib``.
|
|
|
|
:param pkgconf_client_t* client: The client object that owns the package this dependency list belongs to.
|
|
:param pkgconf_list_t* deplist_head: The dependency list to populate with dependency nodes.
|
|
:param char* depends: The dependency data to parse.
|
|
:param uint flags: Any flags to attach to the dependency nodes.
|
|
:return: nothing
|
|
|
|
.. c:function:: void pkgconf_dependency_parse(const pkgconf_client_t *client, pkgconf_pkg_t *pkg, pkgconf_list_t *deplist, const char *depends)
|
|
|
|
Preprocess dependency data and then process that dependency declaration into a dependency list.
|
|
Commas are counted as whitespace to allow for constructs such as ``@SUBSTVAR@, zlib`` being processed
|
|
into ``, zlib``.
|
|
|
|
:param pkgconf_client_t* client: The client object that owns the package this dependency list belongs to.
|
|
:param pkgconf_pkg_t* pkg: The package object that owns this dependency list.
|
|
:param pkgconf_list_t* deplist: The dependency list to populate with dependency nodes.
|
|
:param char* depends: The dependency data to parse.
|
|
:param uint flags: Any flags to attach to the dependency nodes.
|
|
:return: nothing
|
|
|
|
.. c:function:: pkgconf_dependency_t *pkgconf_dependency_copy(pkgconf_client_t *client, const pkgconf_dependency_t *dep)
|
|
|
|
Copies a dependency node to a new one.
|
|
|
|
:param pkgconf_client_t* client: The client object that will own this dependency.
|
|
:param pkgconf_dependency_t* dep: The dependency node to copy.
|
|
:return: a pointer to a new dependency node, else NULL
