io::innerfile
IO::InnerFile(3) User Contributed Perl Documentation IO::InnerFile(3)NAME
IO::InnerFile - define a file inside another file
SYNOPSIS
### Read a subset of a file:
$inner = IO::InnerFile->new($fh, $start, $length);
while (<$inner>) {
...
}
DESCRIPTION
If you have a filehandle that can seek() and tell(), then you can open an IO::InnerFile on a range of the underlying file.
PUBLIC INTERFACE
new FILEHANDLE, [START, [LENGTH]]
Class method, constructor. Create a new inner-file opened on the given FILEHANDLE, from bytes START to START+LENGTH. Both START and
LENGTH default to 0; negative values are silently coerced to zero.
Note that FILEHANDLE must be able to seek() and tell(), in addition to whatever other methods you may desire for reading it.
set_length LENGTH
get_length
add_length NBYTES
Instance methods. Get/set the virtual length of the inner file.
set_start START
get_start
add_start NBYTES
Instance methods. Get/set the virtual start position of the inner file.
binmode
close
flush
getc
getline
print LIST
