Detailed Description

This file deals with embedding the python interpreter within blender, starting and stopping python and exposing blender/python modules so they can be accesses from scripts.

Function Documentation

◆ bpy_context_clear()

◆ BPY_context_dict_clear_members_array()

void BPY_context_dict_clear_members_array ( void ** dict_p,
void * dict_orig,
const char * context_members[],
uint context_members_len )

Use for CTX_*_set(..) functions need to set values which are later read back as expected. In this case we don't want the Python context to override the values as it causes problems see #66256.

Parameters
dict_pA pointer to #bContext.data.py_context so we can assign a new value.
dict_origThe value of #bContext.data.py_context_orig to check if we need to copy.

◆ pystatus_exit_on_error()

void pystatus_exit_on_error ( const PyStatus & status)

Convenience function for BPY_python_start.

These should happen so rarely that having comprehensive errors isn't needed. For example if sys.argv fails to allocate memory.

Show an error just to avoid silent failure in the unlikely event something goes wrong, in this case a developer will need to track down the root cause.
