|
112 |
|
|
*
|
113 |
|
|
* Changes the name of an existing file or directory, from src to dst.
|
114 |
|
|
* If src and dst refer to the same file or directory, does nothing
|
115 |
|
|
* and returns success. Otherwise if dst already exists, it will be
|
116 |
|

* deleted and replaced by src subject to the following conditions:
|
117 |
|
|
* If src is a directory, dst may be an empty directory.
|
118 |
|
|
* If src is a file, dst may be a file.
|
119 |
|
|
* In any other situation where dst already exists, the rename will
|
120 |
|
|
* fail.
|
121 |
|
|
*
|
122 |
|
|
* Results:
|
123 |
|
|
* If the file or directory was successfully renamed, returns TCL_OK.
|
124 |
|
|
* Otherwise the return value is TCL_ERROR and errno is set to
|
125 |
|
|
* indicate the error. Some possible values for errno are:
|
126 |
|
|
*
|
127 |
|
|
* ENAMETOOLONG: src or dst names are too long.
|
128 |
|
|
* EACCES: src or dst parent directory can't be read and/or written.
|
129 |
|
|
* EEXIST: dst is a non-empty directory.
|
130 |
|
|
* EINVAL: src is a root directory or dst is a subdirectory of src.
|
131 |
|
|
* EISDIR: dst is a directory, but src is not.
|
132 |
|
|
* ENOENT: src doesn't exist. src or dst is "".
|
133 |
|
|
* ENOTDIR: src is a directory, but dst is not.
|
134 |
|
|
* EXDEV: src and dst are on different filesystems.
|
135 |
|
|
*
|
136 |
|
|
* EACCES: exists an open file already referring to src or dst.
|
137 |
|
|
* EACCES: src or dst specify the current working directory (NT).
|
138 |
|
|
* EACCES: src specifies a char device (nul:, com1:, etc.)
|
139 |
|
|
* EEXIST: dst specifies a char device (nul:, com1:, etc.) (NT)
|
140 |
|
|
* EACCES: dst specifies a char device (nul:, com1:, etc.) (95)
|
141 |
|
|
*
|
142 |
|
|
* Side effects:
|
143 |
|
|
* The implementation supports cross-filesystem renames of files,
|
144 |
|
|
* but the caller should be prepared to emulate cross-filesystem
|
145 |
|
|
* renames of directories if errno is EXDEV.
