ICorProfilerInfo11::GetEnvironmentVariable method

  • Статия

Gets an environment variable from the process. On non-Windows platforms the runtime keeps an internal cache of environment variables to ensure thread safety. This means that calling getenv will not read any new or updated environment variables set by managed code running in the process after startup.

Syntax

    HRESULT GetEnvironmentVariable(
                [in, string] const WCHAR *szName,
                [in]         ULONG cchValue,
                [out]        ULONG *pcchValue,
                [out, annotation("_Out_writes_to_(cchValue, *pcchValue)")]
                             WCHAR szValue[]);

Parameters

szName
[in] A pointer to a null terminated wide character string containing the name of the environment variable to get.

cchValue
[in] The length, in characters, of szValue.

pcchValue
[out] A pointer to the total character length of szValue.

szValue
[out] A caller provided wide character buffer. When the function returns the buffer will contain the value of the environment variable.
