Detailed Description
Path evaluation context.
Field Documentation
◆ currentloc
| rtems_filesystem_location_info_t rtems_filesystem_eval_path_context_t::currentloc |
This is the current file system location of the evaluation process.
Tokens are evaluated with respect to the current location. The token interpretation may change the current location. The purpose of the path evaluation is to change the start location into a final current location according to the path.
◆ flags
| int rtems_filesystem_eval_path_context_t::flags |
The path evaluation is controlled by the following flags.
- RTEMS_FS_PERMS_READ,
- RTEMS_FS_PERMS_WRITE,
- RTEMS_FS_PERMS_EXEC,
- RTEMS_FS_FOLLOW_HARD_LINK,
- RTEMS_FS_FOLLOW_SYM_LINK,
- RTEMS_FS_MAKE,
- RTEMS_FS_EXCLUSIVE,
- RTEMS_FS_ACCEPT_RESIDUAL_DELIMITERS, and
- RTEMS_FS_REJECT_TERMINAL_DOT.
◆ recursionlevel
| int rtems_filesystem_eval_path_context_t::recursionlevel |
Symbolic link evaluation is a recursive operation.
This field helps to limit the recursion level and thus prevents a stack overflow. The recursion level is limited by RTEMS_FILESYSTEM_SYMLOOP_MAX.
◆ startloc
| rtems_filesystem_global_location_t* rtems_filesystem_eval_path_context_t::startloc |
The start location of the evaluation process.
The start location my change during symbolic link evaluation.
