ICorProfilerInfo7::ReadInMemorySymbols

  • Article

[Supported in the .NET Framework 4.6.1 and later versions]

Reads bytes from an in-memory symbol stream.

Syntax

HRESULT ReadInMemorySymbols(  
        [in] ModuleID moduleId,  
        [in] DWORD symbolsReadOffset,  
        [out] BYTE* pSymbolBytes,  
        [in] DWORD countSymbolBytes,  
        [out] DWORD* pCountSymbolBytesRead  
);

Parameters

moduleId
[in] The identifier of the module containing the in-memory stream.

symbolsReadOffset
[in] The offset within the in-memory stream at which to start reading bytes.

pSymbolBytes
[out] A pointer to the buffer to which the data will be copied. The buffer should have countSymbolBytes of space available.

countSymbolBytes
[in] The number of bytes to copy.

pCountSymbolBytesRead
[out] When the method returns, contains the actual number of bytes read.

Return Value

S_OK, if a non-zero number of bytes were read.

CORPROF_E_MODULE_IS_DYNAMIC, if the module was created using System.Reflection.Emit.

Remarks

The ReadInMemorySymbols method attempts to read countSymbolBytes of data starting at offset symbolsReadOffset within the in-memory stream. The data is copied to pSymbolBytes, which is expected to have countSymbolBytes of space available. pCountSymbolsBytesRead contains the actual number of bytes read, which may be less than countSymbolBytes if the end of the stream is reached.

Note

The current implementation does not support Reflection.Emit. If the module was created by using Reflection.Emit, the method returns CORPROF_E_MODULE_IS_DYNAMIC.
