/*

 * 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.
