NAME
binmode - prepare binary files on old systems
SYNOPSIS
binmode FILEHANDLE
DESCRIPTION
Arranges for the file to be read or written in ``binary'' mode in operating systems that distinguish between binary and text files. Files that are not in binary mode have
CR
LF sequences translated to
LF on input and
LF translated to
CR
LF on output. Binmode has no effect under Unix; in
MS-DOS and similarly archaic systems, it may be imperative--otherwise your MS-DOS-damaged
C library may mangle your file. The key distinction between systems that need
binmode() and those that don't is their text file formats. Systems like Unix, MacOS, and Plan9 that delimit lines with a single character, and that encode that character in
C as
"\n", do not need
binmode(). The rest need it. If
FILEHANDLE is an expression, the value is taken as the
name of the filehandle.
DISCLAIMER
We are painfully aware that these documents may contain incorrect links and misformatted HTML. Such bugs lie in the automatic translation process that automatically created the hundreds and hundreds of separate documents that you find here. Please do not report link or formatting bugs, because we cannot fix per-document problems. The only bug reports that will help us are those that supply working patches to the installhtml or pod2html programs, or to the Pod::HTML module itself, for which I and the entire Perl community will shower you with thanks and praises.If rather than formatting bugs, you encounter substantive content errors in these documents, such as mistakes in the explanations or code, please use the perlbug utility included with the Perl distribution.
