1185 * lpResult [O] Points to a buffer into which the executable path is
1186 * copied. This parameter must not be NULL otherwise
1187 * FindExecutable() segfaults. The buffer must be of size at
1188 * least MAX_PATH characters.
1189 *
1190 * RETURNS
1191 * A value greater than 32 on success, less than or equal to 32 otherwise.
1192 * See the SE_ERR_* constants.
1193 *
1194 * NOTES
1195 * On Windows XP and 2003, FindExecutable() seems to first convert the
1196 * filename into 8.3 format, thus taking into account only the first three
1197 * characters of the extension, and expects to find an association for those.
1198 * However other Windows versions behave sanely.
