60 * Parse an include statement. Each call returns a file name, along with
61 * (possibly) a specific map in the file, an explicit group designator, and
62 * the separator from the next file, used to determine the merge mode.
64 * @param str_inout Input statement, modified in-place. Should be passed in
65 * repeatedly. If str_inout is NULL, the parsing has completed.
67 * @param file_rtrn Set to the name of the include file to be used. Combined
68 * with an enum xkb_file_type, this determines which file to look for in the
71 * @param map_rtrn Set to the string between '(' and ')', if any. This will
72 * result in the compilation of a specific named map within the file (e.g.
73 * xkb_symbols "basic" { ... }) , as opposed to the default map of the file.
75 * @param nextop_rtrn Set to the next operation in the complete statement,
76 * which is '\0' if it's the last file or '+' or '|' if there are more.
77 * Separating the files with '+' sets the merge mode to MERGE_MODE_OVERRIDE,
78 * while '|' sets the merge mode to MERGE_MODE_AUGMENT.
80 * @param extra_data Set to the string after ':', if any. Currently the
81 * extra data is only used for setting an explicit group index for a symbols
84 * @return true if parsing was successful, false for an illegal string.
86 * Example: "evdev+aliases(qwerty):2"

93 * 2nd run with "aliases(qwerty):2"
