format
This patch adds some functions to manage the printing of the data in
tabular format.
The function
struct string_table *table_create(int columns, int rows)
creates an (empty) table.
The functions
char *table_printf(struct string_table *tab, int column,
int row, char *fmt, ...)
char *table_vprintf(struct string_table *tab, int column,
int row, char *fmt, va_list ap)
populate the table with text. To align the text to the left, the text
shall be prefixed with '<', otherwise the text shall be prefixed by a
'>'. If the first character is a '=', the the text is replace by a
sequence of '=' to fill the column width.
The function
void table_free(struct string_table *)
frees all the data associated to the table.
The function
void table_dump(struct string_table *tab)
prints the table on stdout.
