Typedef Documentation

typedef struct PmVmGlobal_s PmVmGlobal_t

This struct contains ALL of PyMite's globals

---

Function Documentation

PmReturn_t global_init

(

void

)

Initializes the global struct

Returns:

Return status

PmReturn_t global_loadBuiltins

(

void

)

Loads the "__bt" module and sets the builtins dict (PM_PBUILTINS) to point to __bt's attributes dict. Creates "None" = None entry in builtins.

When run, there should not be any other threads in the interpreter thread list yet.

Returns:

Return status

PmReturn_t global_setBuiltins

(

pPmFunc_t

pmod

)

Sets the builtins dict into the given module's attrs.

If not yet done, loads the "__bt" module via global_loadBuiltins(). Restrictions described in that functions documentation apply.

Parameters:

pmod

Module whose attrs receive builtins

Returns:

Return status

Variable Documentation

volatile PmVmGlobal_t gVmGlobal
