stdio_stream_default_env() specifications

Signature

stdio_stream_env_t stdio_stream_default_env(
    const osal_stdio_ops_t *stdio_ops,
    const osal_mem_ops_t *mem,
    const stream_env_t *port_env);

Purpose

Build a default environment for the stdio_stream adapter.

Preconditions

• stdio_ops must designate a valid OSAL stdio operations table.
• mem must designate a valid OSAL memory operations table.
• port_env must designate a valid stream port environment object.

Invalid arguments

• None.

Success

• Returns a well-formed stdio_stream_env_t.
• Stores stdio_ops into ret.stdio_ops.
• Stores mem into ret.mem.
• Copies *port_env into ret.port_env.

Failure

• None.

Notes

• This helper packages borrowed dependencies into a value-initialized stdio_stream_env_t.
• The returned environment does not take ownership of any pointer passed as argument.
• ret.stdio_ops provides the borrowed OSAL stdio boundary used by the adapter backend to access the standard streams and the stdio primitives required to implement the stream port contract.
• This helper does not allocate.
