| 43 | =head1 DESCRIPTION | ||||
| 44 | |||||
| 45 | C<IO::File> inherits from C<IO::Handle> and C<IO::Seekable>. It extends | ||||
| 46 | these classes with methods that are specific to file handles. | ||||
| 47 | |||||
| 48 | =head1 CONSTRUCTOR | ||||
| 49 | |||||
| 50 | =over 4 | ||||
| 51 | |||||
| 52 | =item new ( FILENAME [,MODE [,PERMS]] ) | ||||
| 53 | |||||
| 54 | Creates an C<IO::File>. If it receives any parameters, they are passed to | ||||
| 55 | the method C<open>; if the open fails, the object is destroyed. Otherwise, | ||||
| 56 | it is returned to the caller. | ||||
| 57 | |||||
| 58 | =item new_tmpfile | ||||
| 59 | |||||
| 60 | Creates an C<IO::File> opened for read/write on a newly created temporary | ||||
| 61 | file. On systems where this is possible, the temporary file is anonymous | ||||
| 62 | (i.e. it is unlinked after creation, but held open). If the temporary | ||||
| 63 | file cannot be created or opened, the C<IO::File> object is destroyed. | ||||
| 64 | Otherwise, it is returned to the caller. | ||||
| 65 | |||||
| 66 | =back | ||||
| 67 | |||||
| 68 | =head1 METHODS | ||||
| 69 | |||||
| 70 | =over 4 | ||||
| 71 | |||||
| 72 | =item open( FILENAME [,MODE [,PERMS]] ) | ||||
| 73 | |||||
| 74 | =item open( FILENAME, IOLAYERS ) | ||||
| 75 | |||||
| 76 | C<open> accepts one, two or three parameters. With one parameter, | ||||
| 77 | it is just a front end for the built-in C<open> function. With two or three | ||||
| 78 | parameters, the first parameter is a filename that may include | ||||
| 79 | whitespace or other special characters, and the second parameter is | ||||
| 80 | the open mode, optionally followed by a file permission value. | ||||
| 81 | |||||
| 82 | If C<IO::File::open> receives a Perl mode string ("E<gt>", "+E<lt>", etc.) | ||||
| 83 | or an ANSI C fopen() mode string ("w", "r+", etc.), it uses the basic | ||||
| 84 | Perl C<open> operator (but protects any special characters). | ||||
| 85 | |||||
| 86 | If C<IO::File::open> is given a numeric mode, it passes that mode | ||||
| 87 | and the optional permissions value to the Perl C<sysopen> operator. | ||||
| 88 | The permissions default to 0666. | ||||
| 89 | |||||
| 90 | If C<IO::File::open> is given a mode that includes the C<:> character, | ||||
| 91 | it passes all the three arguments to the three-argument C<open> operator. | ||||
| 92 | |||||
| 93 | For convenience, C<IO::File> exports the O_XXX constants from the | ||||
| 94 | Fcntl module, if this module is available. | ||||
| 95 | |||||
| 96 | =item binmode( [LAYER] ) | ||||
| 97 | |||||
| 98 | C<binmode> sets C<binmode> on the underlying C<IO> object, as documented | ||||
| 99 | in C<perldoc -f binmode>. | ||||
| 100 | |||||
| 101 | C<binmode> accepts one optional parameter, which is the layer to be | ||||
| 102 | passed on to the C<binmode> call. | ||||
| 103 | |||||
| 104 | =back | ||||
| 105 | |||||
| 106 | =head1 NOTE | ||||
| 107 | |||||
| 108 | Some operating systems may perform C<IO::File::new()> or C<IO::File::open()> | ||||
| 109 | on a directory without errors. This behavior is not portable and not | ||||
| 110 | suggested for use. Using C<opendir()> and C<readdir()> or C<IO::Dir> are | ||||
| 111 | suggested instead. | ||||
