|
static |
close a file
Closes a file opened by PosixFSWrapper::OpenFile().
|
static |
create a directory
Creates a new directory.
|
static |
create a temporary file name
|
static |
delete an empty directory
Delete an empty directory.
Returns true if the operation was successful.
|
static |
delete a file
Deletes a file.
Returns true if the operation was successful. The delete will fail if the fail doesn't exist or the file is read-only.
|
static |
return true if a directory exists
Return true if a directory exists.
|
static |
return true if at end-of-file
Returns true if current position is at end of file.
|
static |
return true if a file exists
Return true if a file exists.
|
static |
flush a file
Flush unwritten data to file.
|
static |
get path to the current bin directory (for bin: standard assign)
This method sould return the directory where the application executable is located.
|
static |
get size of a file in bytes
Returns the size of a file in bytes.
|
static |
get the last write-access time stamp of a file
Return the last write-access time to a file.
|
static |
get path to the current application directory (for home: standard assign)
This method should return the installation directory of the application.
Under Nebula, this is either the directory where the executable is located, or 2 levels above the executable (if it is in home:bin/posix).
|
static |
get path to the current user's temp directory (for temp: standard assign)
This method should return a directory for temporary files with read/write access for the current user.
|
static |
get path to the current user's home directory (for user: standard assign)
This method should return the path to the current user's home directory.
This is the directory where application can write their data to. Under windows, this is the "My Files" directory.
|
static |
return true when the string is a device name (e.g. "C:")
|
static |
get locked status of file
try to check for a lock by trying to lock the file.
inherently racey, but good enough in some situations
|
static |
get read-only status of a file
Get the read-only status of a file.
|
static |
list all subdirectories in a directory
Lists all subdirectories in a directory, filtered by a pattern.
This will not return the special directories ".." and ".".
|
static |
list all files in a directory
Lists all files in a directory, filtered by a pattern.
|
static |
map file to virtual memory
|
static |
open a file
Open a file using the Posix function CreateFile().
Returns a handle to the file which must be passed to the other PosixFSWrapper file methods. If opening the file fails, the function will return 0. The filename must be a native Posix path (no assigns, etc...).
|
static |
read from a file
Read data from a file, returns number of bytes read.
|
static |
rename a file
|
static |
seek in a file
Seek in a file.
|
static |
set the write-access time stamp of a file
|
static |
set read-only status of a file
Set the read-only status of a file.
|
static |
get position in file
Get current position in file.
|
static |
unmap file
|
static |
write to a file
Write data to a file.
