Note that the forward slash character ('/') has a special meaning in |
7249 |
|
filename / path based arguments: it acts as separator of the nodes in |
7250 |
|
the path, thus if a directory- or filename includes a forward slash |
7251 |
|
(not intended as path node separator), you MUST escape that slash |
7252 |
|
either with the respective hex escape sequence ("\x2f") or with the |
7253 |
|
respective octal escape sequence ("\057"). |

|
Note for Windows: file path arguments in LSCP are expected |
7258 |
|
to use forward slashes as directory node separator similar |
7259 |
|
to Unix based operating systems. In contrast to Unix however |
7260 |
|
a Windows typical drive character is expected to be |
7261 |
|
prefixed to the path. That is an original Windows file path |
7262 |
|
like "D:\Sounds\My.gig" would become in LSCP: |
7263 |
|
"D:/Sounds/My.gig". |
