Macros for Automatic Global Variable Creation Пред.
Глава 53. Creating Variables
- In addition to the macros discussed earlier, a few macros allow
easy creation of simple global variables. These are nice to know
in case you want to introduce global flags, for example. This is
somewhat bad practice, but Table Табл. 53-5
describes macros that do
exactly this task. They don't need any zval
allocation; you simply have to supply a variable name and value.
Таблица 53-5. Macros for Global Variable Creation
| Macro | Description |
| SET_VAR_STRING(name, value) | Creates a new string. |
| SET_VAR_STRINGL(name, value,
length) | Creates a new string of the specified length. This macro
is faster than SET_VAR_STRING and also binary-safe. |
| SET_VAR_LONG(name, value) | Creates a new long. |
| SET_VAR_DOUBLE(name, value) | Creates a new double. |
