2. 6 libraries.module \libraries_get_libraries()
3. 7.3 libraries.module \libraries_get_libraries()
4. 7.2 libraries.module \libraries_get_libraries()

Returns an array of library directories.

Returns an array of library directories from the all-sites directory (i.e. sites/all/libraries/), the profiles directory, and site-specific directory (i.e. sites/somesite/libraries/). The returned array will be keyed by the library name. Site-specific libraries are prioritized over libraries in the default directories. That is, if a library with the same name appears in both the site-wide directory and site-specific directory, only the site-specific version will be listed.

Return value

A list of library directories.
