Detailed Description
Shared-strings defines.
Definition in file shstr.h.
Define Documentation
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 49 of file shstr.h.
| #define REFCOUNT_TYPE long |
In the unlikely occurrence 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 57 of file shstr.h.
SS(string) will return the address of the shared_string struct which contains "string".
Definition at line 68 of file shstr.h.
The size of the shared strings hashtable.
Definition at line 35 of file shstr.h.
Typedef Documentation
One actual shared string.
