In case of + sd_path_lookup() a single NUL-terminated string is returned. + When type specifies a set of paths, they are concatenated using + : as a separator (as is traditionally done for e.g. $PATH or + $LD_LIBRARY_PATH). In case of sd_path_lookup_strv() a + NULL-terminated array of strings is returned (strv). If suffix + suffix is given, it is concatenated to each of the paths after a slash + (/). All returned paths are absolute. + + For paths which refer to user directories, the relevant XDG standard is followed, with support for + environment variables like $XDG_DOCUMENTS_DIR, $XDG_DESKTOP_DIR, + ..., and explicit configuration in /etc/xdg/user-dirs.conf or + ${XDG_CONFIG_HOME}/user-dirs.dirs. See + + XDG Base Directory Specification for details. + + systemd-path1 is + a wrapper around sd_path_lookup() and allows the same set of paths to be queried. + + + + + Return Value + + On success, sd_path_lookup() and sd_path_lookup_strv() + return a non-negative integer. On failure, a negative errno-style error number is returned by either + function. + + The returned string or string array (strv) must be + free3'd by the + caller. + + + Errors + + Returned errors may indicate the following problems: + + + + -EOPNOTSUPP + + Unknown identifier type. + + + + -EINVAL + + Output argument is NULL. + + + + -ENOMEM + + Memory allocation failed. + + + + + + + Examples + + + Look up the location of ~/Documents + + + Note that the default answer of $HOME/Documents may be + overridden by user-dirs.conf or + $XDG_DOCUMENTS_DIR. + + + + + + + See Also + + + systemd-path1 + + + + -- cgit v1.2.1
