22 * blkid_get_devname() is primarily intended for parsing "NAME=value"
23 * tokens. It will return the device matching the specified token, NULL if
24 * nothing is found, or copy of the string if it's not in "NAME=value"
26 * get_devname() takes the same parameters and works the same way as
27 * blkid_get_devname() except it can handle '=' in the file name.
29 char *get_devname(blkid_cache cache, const char *token, const char *value)
38 ret = blkid_get_devname(cache, token, value);
42 if (access(token, F_OK) == 0)
45 ret = blkid_get_devname(cache, token, NULL);
48 * In case of collision prefer the result from
49 * blkid_get_devname() to avoid a file masking file system with
52 if (is_file && (strcmp(ret, token) != 0)) {
54 _("Collision found: '%s' refers to both '%s' "
55 "and a file '%s'. Using '%s'!\n"),
56 token, ret, token, ret);
