76  * Data structures and routines for printing output.
77  * All non-parseable output is assumed to be in a columnar format.
78  * Multiple fields in parsable output are separated by ':'; single
79  * field output is printed as-is.
80  *
81  * Each sub-command is associated with a global array of pointers,
82  * print_field_t *fields[], where the print_field_t contains information
83  * about the format in which the output is to be printed.
84  *
85  * Sub-commands may be implemented in one of two ways:
86  * (i)  the implementation could get all field values into a character
87  *      buffer, with pf_offset containing the offset (for pf_name) within
88  *      the buffer. The sub-command would make the needed system calls
89  *      to obtain all possible column values and then invoke the
90  *      dladm_print_field() function to print the specific fields
91  *      requested in the command line. See the comments for dladm_print_field
92  *      for further details.
93  * (ii) Alternatively, each fields[i] entry could store a pf_index value
94  *      that uniquely identifies the column to be printed. The implementation
95  *      of the sub-command would then invoke dladm_print_output() with a
96  *      callback function whose semantics are described below (see comments
97  *      for dladm_print_output())
98  *
99  * Thus, an implementation of a sub-command must provide the following:
100  *
101  * static print_field_t sub_command_fields[] = {
102  *	{<name>, <header>,<field width>,  <offset_or_index>, cmdtype},
103  *	:
104  *	{<name>, <header>,<field width>,  <offset_or_index>, cmdtype}
105  * };
106  *
107  * #define	SUB_COMMAND_MAX_FIELDS sizeof \
108  *		(sub_comand_fields) / sizeof (print_field_t))
109  *
110  * print_state_t sub_command_print_state;
111  *
112  * The function that parses command line arguments (typically
113  * do_sub_command()) should then contain an invocation like:
114  *
115  *	fields = parse_output_fields(fields_str, sub_command_fields,
116  *	    SUB_COMMAND_MAX_FIELDS, CMD_TYPE_ANY, &nfields);
117  *
118  * and store the resulting fields and nfields value in a print_state_t
119  * structure tracked for the command.
120  *
121  *	sub_command_print_state.ps_fields = fields;
122  *	sub_command_print_state.ps_nfields = nfields;
123  *
124  * To print the column header for the output, the print_header()
125  * function must then be invoked by do_sub_command().
126  *
127  * Then if method (i) is used for the sub_command, the do_sub_command()
128  * function should make the necessary system calls to fill up the buffer
129  * and then invoke dladm_print_field(). An example of this method is
130  * the implementation of do_show_link() and show_link();
131  *
132  * If method (ii) is used, do_sub_command should invoke dladm_print_output()
133  * with a callback function that will be called for each field to be printed.
134  * The callback function will be passed a pointer to the print_field_t
135  * for the field, and the pf_index may then be used to identify the
136  * system call required to find the value to be printed. An example of
137  * this implementation may be found in the do_show_dev() and print_dev()
138  * invocation.
