add_to_standard_headers()

void add_to_standard_headers	(	char *	name_header,
		char *	unit_header,
		char *	printf_string,
		char *	new_name,
		char *	new_unit,
		char *	new_format,
		long	min_width )

Adds new standard headers to name, unit, and printf string headers.

This function facilitates adding a new set of standard headers, including name, unit, and format strings, to the respective header arrays. It ensures that the new headers conform to the specified minimum width.

Parameters

name_header	The header string for names.
unit_header	The header string for units.
printf_string	The header string for printf format specifiers.
new_name	The new name to add to the name header.
new_unit	The new unit to add to the unit header.
new_format	The new format specifier to add to the printf string header.
min_width	The minimum acceptable width for the new headers.
