Dump in hexadecimal the content of a scalar. The result is returned in a string. Each line of the result consists of the offset in the source in the leftmost column of each line, followed by one or more columns of data from the source in hexadecimal. The rightmost column of each line shows the printable characters (all others are shown as single dots).

Data::Hexdumper provides a simple way to format and display arbitrary binary data in a way similar to how some debuggers do for lesser languages. It gives the programmer a considerable degree of flexibility in how the data is formatted, with sensible defaults. It is envisaged that it will primarily be of use for those wrestling alligators in the swamp of binary file formats, which is why it was written in the first place.

Hexify formats arbitrary (possible binary) data into a format suitable for hex dumps in the style of xd or hexl.

DIO provides functions and stream wrappers which provide raw and serial low level IO support. The use of the DIO functions should be considered only when direct control of a device is needed. In all other cases, the standard filesystem functions are more than adequate.

This extension provides interface to the libeio library. Libeio is a an asynchronous I/O library. Features basically include asynchronous versions of POSIX API(read, write, open, close, stat, unlink, fdatasync, mknod, readdir etc.); sendfile (native on Solaris, Linux, HP-UX, FreeBSD); readahead. libeio itself emulates the system calls, if they are not available on specific(UNIX-like) platform.

Hierarchy-wide accumulation of list and hash results. This is a mixin class. By inheriting from it you get two methods that are able to accumulate hierarchy-wide list and hash results.

This module is about the native integer numerical data type. A native integer is one of the types of datum that can appear in the numeric part of a Perl scalar. This module supplies constants describing the native integer type. There are actually two native integer representations: signed and unsigned. Both are handled by this module.

This extension allows to interact with processes through PTY, using expect library.

This extension uses libgearman library to provide API for communicating with gearmand, and writing clients and workers.
