    To check a particular path element

    To check a particular path element p, Kpathsea first checks if a prebuilt database (see “Filename database” on page 82) applies to p, i.e., if the database is in a directory that is a prefix of p. If so, the path specification is matched against the contents of the database. -

    Although the simplest and most common path element is a directory name, Kpathsea supports additional features in search paths: layered default values, environment variable names, config file values, users’ home directories, and recursive subdirectory searching. Thus, we say that Kpathsea expands a path element, meaning it transforms all the specifications into basic directory name or names. This is described in the following sections in the same order as it takes place. -
