};int sd_path_lookup(uint64_t type, const char *suffix, char **paths); int sd_path_lookup_strv(uint64_t type, const char *suffix, char ***paths);
DESCRIPTIONsd_path_lookup() and sd_bus_path_lookup_strv() return a single path or set of file system paths specified by the argument type. 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[1] for details. systemd-path(1) is a wrapper around sd_path_lookup() and allows the same set of paths to be queried.
RETURN VALUEOn 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 free(3)'d by the caller.
ErrorsReturned errors may indicate the following problems: −EOPNOTSUPP Unknown identifier type. −EINVAL Output argument is NULL. −ENXIO Query failed because of an undefined environment variable (e.g. for SD_PATH_USER_RUNTIME when $XDG_RUNTIME_DIR is not defined). −ENOMEM Memory allocation failed.
EXAMPLES
Look up the location of ~/Documents/* SPDX−License−Identifier: CC0−1.0 */
#include <stdio.h>
#include <stdlib.h>
#include <sd−path.h>
int main(void) {
int r;
char *t;
r = sd_path_lookup(SD_PATH_USER_DOCUMENTS, NULL, &t);
if (r < 0)
return EXIT_FAILURE;
printf("~/Documents: %s\n", t);
free(t);
return EXIT_SUCCESS;
}Note that the default answer of $HOME/Documents may be overridden by user−dirs.conf or $XDG_DOCUMENTS_DIR.
NOTESThese APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.
