Like printf, reprint also has conversion specifiers to control data formatting. The conversion specifier breaks down to the following parts

1. Field Header: Indicates start of conversion specifier. The \f header starts a formatted specifier, while \b header starts a binary output specifier.
2. Packing Directive: Specify whether source data is tightly packed or packed as a C struct.
3. Output Control: Various parameters for controlling output.
4. Input Specification: Various parameters for interpreting the input. At minimum there is a size specification, which terminates the conversion specifier.

The exact characters comprising these sections are shown in the ASCII table breakdown of the conversion specifier syntax.
