Function rb_internal_thread_specific_key_create 

pub unsafe extern "C" fn rb_internal_thread_specific_key_create() -> rb_internal_thread_specific_key_t

Create a key to store thread specific data.

These APIs are designed for tools using rb_internal_thread_event_hook APIs.

Note that only RB_INTERNAL_THREAD_SPECIFIC_KEY_MAX keys can be created. raises ThreadError if exceeded.

Usage: // at initialize time: int tool_key; // gvar Init_tool() { tool_key = rb_internal_thread_specific_key_create; }

// at any timing: rb_internal_thread_specific_setthread, tool_key, per_thread_data); … per_thread_data = rb_internal_thread_specific_getthread, tool_key);
