JS_GetRuntimePrivate 编辑

Access a JSRuntime field for application-specific data.

Syntax

void *
JS_GetRuntimePrivate(JSRuntime *rt);

void
JS_SetRuntimePrivate(JSRuntime *rt, void *data);

Description

Each JSRuntime has a field of type void * which the application may use for any purpose. It is especially useful for storing data which callbacks may then easily access. JS_GetRuntimePrivate gets the value of this field and JS_SetRuntimePrivate sets it. The field is initially NULL.

Memory management for this private data is the application's responsibility. The JavaScript engine itself never uses it.
