/*
 * The arg_hdr struct defines properties that are common to all arg_xxx structs.
 * The argtable library requires each arg_xxx struct to have an arg_hdr
 * struct as its first data member.
 * The argtable library functions then use this data to identify the
 * properties of the command line option, such as its option tags,
 * datatype string, and glossary strings, and so on.
 * Moreover, the arg_hdr struct contains pointers to custom functions that
 * are provided by each arg_xxx struct which perform the tasks of parsing
 * that particular arg_xxx arguments, performing post-parse checks, and
 * reporting errors.
 * These functions are private to the individual arg_xxx source code
 * and are the pointer to them are initiliased by that arg_xxx struct's
 * constructor function. The user could alter them after construction
 * if desired, but the original intention is for them to be set by the
 * constructor and left unaltered.
