perl5/File::Copy(3) -- Copy files or filehandles
|
|
The File::Copy module provides two basic functions, copy and move, which are useful for getting the contents of a file from one place to another. o The copy function takes two parameters: a file to copy from and a file to copy to. Either argument may be a string, a FileHandle reference or a FileHandle glob. Obviously, if the first argument is a filehandle of some sort, it will be read from, and if it is a file name it will be opened for reading. Likewise, the second argument will be written to (... |

perl5/File::DosGlob(3) -- a more capable perlglob.exe replacement
|
|
A module that implements DOS-like globbing with a few enhancements. This file is also a portable replacement for perlglob.exe. It is largely compatible with perlglob.exe (the M$ setargv.obj version) in all but one respect--it understands wildcards in directory components. For example, C<<..\\l*b\\file/*glob.p?>> will work as expected (in that it will find something like '..\lib\File/DosGlob.pm' alright). Note that all path components are case-insensitive, and that backslashes and forward... |

perl5/File::Find(3) -- traverse a directory structure depth-first
|
|
The wanted() function does whatever verifications you want. $File::Find::dir contains the current directory name, and $_ the current filename within that directory. $File::Find::name contains "$File::Find::dir/$_". You are chdir()'d to $File::Find::dir when the function is called. The function may set $File::Find::prune to prune the tree. File::Find assumes that you don't alter the $_ variable. If you do then make sure you return it to its original value before exiting your function. This li... |

perl5/File::Path(3) -- create or remove a series of directories
|
|
The mkpath function provides a convenient way to create directories, even if your mkdir kernel call won't create more than one level of directory at a time. mkpath takes three arguments: o the name of the path to create, or a reference to a list of paths to create, o a boolean value, which if TRUE will cause mkpath to print the name of each directory as it is created (defaults to FALSE), and o the numeric mode to use when creating the directories (defaults to 0777) It returns a list of all dire... |
|
perl5/File::stat(3) -- by-name interface to Perl's built-in stat() functions
|
|
This module's default exports override the core stat() and lstat() functions, replacing them with versions that return "File::stat" objects. This object has methods that return the similarly named structure field name from the stat(2) function; namely, dev, ino, mode, nlink, uid, gid, rdev, size, atime, mtime, ctime, blksize, and blocks. You may also import all the structure fields directly into your namespace as regular variables using the :FIELDS import tag. (Note that this still overrides ... |
|
c++/filebuf(3) -- buffer for file I/O.
|
|
filebufs specialize streambufs to use a file as a source or sink of characters. Characters are consumed by doing writes to the file, and are produced by doing reads. When the file is seekable, a filebuf allows seeks. At least 4 characters of putback are guaranteed. When the file permits reading and writing, the filebuf permits both storing and fetching. No special action is required between gets and puts (u... |
|
perl5/FileCache(3) -- keep more files open than the system permits
|
|
The cacheout function will make sure that there's a filehandle open for writing available as the pathname you give it. It automatically closes and re-opens files if you exceed your system file descriptor maximum. |
|
Tk/fileevent(3) -- Execute a script when a file becomes readable or writable
|
|
This command is used to create file event handlers. A file event handler is a binding between a file and a script, such that the script is evaluated whenever the file becomes readable or writable. File event handlers are most commonly used to allow data to be received from a child process on an event-driven basis, so that the receiver can continue to interact with the user while waiting for the data to arrive. If an application invokes gets or read when there is no input data available, the proc... |
|
perl5/FileHandle(3) -- supply object methods for filehandles
|
|
NOTE: This class is now a front-end to the IO::* classes. FileHandle::new creates a FileHandle, which is a reference to a newly created symbol (see the Symbol package). If it receives any parameters, they are passed to FileHandle::open; if the open fails, the FileHandle object is destroyed. Otherwise, it is returned to the caller. FileHandle::new_from_fd creates a FileHandle like new does. It requires two parameters, which are passed to FileHandle::fdopen; if the fdopen fails, the FileHandle obj... |

Tk/filehndlr(3) -- associate procedure callbacks with files or devices
|
|
int id (in) Integer identifier for an open file or device (such as returned by open system call). int mask (in) Conditions under which proc should be called: OR-ed combination of TK_READABLE, TK_WRITABLE, and TK_EXCEPTION. Tk_FileProc *proc (in) Procedure to invoke whenever the file or device indicated by id meets the conditions specified by mask. Tk_FileProc2 *proc2 (in) Procedure to invoke from event loop to check whether fd is ready and, if so, handle it. ClientData clientData (in) Arbitrary ... |
|
perl5/FindBin(3) -- Locate directory of original perl script
|
|
Locates the full path to the script bin directory to allow the use of paths relative to the bin directory. This allows a user to setup a directory tree for some software with directories /bin and /lib and then the above example will allow the use of modules in the lib directory without knowing where the software tree is installed. If perl is invoked using the -e option or the perl script is read from STDIN then FindBin sets both $Bin and $RealBin to the current directory.... |

Tk/findphoto(3) -- manipulate the image data stored in a photo image.
|
|
char *imageName (in) Name of the photo image. Tk_PhotoHandle handle (in) Opaque handle identifying the photo image to be affected. Tk_PhotoImageBlock *blockPtr (in) Specifies the address and storage layout of image data. int x (in) Specifies the X coordinate where the top-left corner of the block is to be placed within the image. int y (in) Specifies the Y coordinate where the top-left corner of the block is to be placed Page 1 Tk_FindPhoto(3Tk) Tk_FindPhoto(3Tk) within the image. int width (in)... |
