Macro Definition Documentation

#define GATHER ( n )

Definition at line 60 of file shstr.h.

Referenced by add_refcount(), add_string(), find_string(), free_string(), and hashstr().

#define MAXSTRING 20

This specifies how many characters the hashing routine should look at. You may actually save CPU by increasing this number if the typical string is large.

Definition at line 21 of file shstr.h.

#define offsetof	(	type,
		member
	)	(int)&(((type *)0)->member)

The offsetof macro is part of ANSI C, but many compilers lack it, for example "gcc -ansi"

Definition at line 37 of file shstr.h.

Referenced by clear_object(), copy_object(), and get_player().

#define PADDING ((2*sizeof(long)-sizeof(REFCOUNT_TYPE))%sizeof(long))+1

Definition at line 65 of file shstr.h.

Referenced by new_shared_string().

#define REFCOUNT_TYPE int

In the unlikely occurence that 16383 references to a string are too few, you can modify the below type to something bigger. (The top bit of "refcount" is used to signify that "u.array" points at the array entry.)

Definition at line 30 of file shstr.h.

#define SS ( x ) ((shared_string *) ((x)-offsetof(shared_string, string)))

SS(string) will return the address of the shared_string struct which contains "string".

#define SS_DUMP_TABLE 1

Definition at line 46 of file shstr.h.

Referenced by command_ssdumptable(), and ss_dump_table().

#define SS_DUMP_TOTALS 2

Definition at line 47 of file shstr.h.

Referenced by command_strings(), and ss_dump_table().
