D3DX10CompileFromMemory function
Note
Instead of using this legacy function, we recommend that you compile offline by using the Fxc.exe command-line compiler or use the D3DCompile API.
Compile a shader or an effect that is loaded in memory.
Syntax
HRESULT D3DX10CompileFromMemory(
_In_ LPCSTR pSrcData,
_In_ SIZE_T SrcDataLen,
_In_ LPCSTR pFileName,
_In_ const D3D10_SHADER_MACRO *pDefines,
_In_ LPD3D10INCLUDE pInclude,
_In_ LPCSTR pFunctionName,
_In_ LPCSTR pProfile,
_In_ UINT Flags1,
_In_ UINT Flags2,
_In_ ID3DX10ThreadPump *pPump,
_Out_ ID3D10Blob **ppShader,
_Out_ ID3D10Blob **ppErrorMsgs,
_Out_ HRESULT *pHResult
);
Parameters
-
pSrcData [in]
-
Type: LPCSTR
Pointer to the shader in memory.
-
SrcDataLen [in]
-
Type: SIZE_T
Size of the shader in memory.
-
pFileName [in]
-
Type: LPCSTR
The name of the file that contains the shader code.
-
pDefines [in]
-
Type: const D3D_SHADER_MACRO*
Optional. Pointer to an array of macro definitions (see D3D_SHADER_MACRO). The last structure in the array serves as a terminator and must have all members set to 0. If not used, set pDefines to NULL.
-
pInclude [in]
-
Type: LPD3D10INCLUDE
Optional. Pointer to an ID3D10Include Interface interface for handling include files. Setting this to NULL will cause a compile error if a shader contains a #include.
-
pFunctionName [in]
-
Type: LPCSTR
Name of the shader-entry point function where shader execution begins. When you compile an effect, D3DX10CompileFromMemory ignores pFunctionName; we recommend that you set pFunctionName to NULL because it is good programming practice to set a pointer parameter to NULL if the called function will not use it.
-
pProfile [in]
-
Type: LPCSTR
A string that specifies the shader model; can be any profile in shader model 2, shader model 3, or shader model 4.
-
Flags1 [in]
-
Type: UINT
-
Flags2 [in]
-
Type: UINT
Effect compile flags. When you compile a shader and not an effect file, D3DX10CompileFromMemory ignores Flags2; we recommend that you set Flags2 to zero because it is good programming practice to set a nonpointer parameter to zero if the called function will not use it.
-
pPump [in]
-
Type: ID3DX10ThreadPump*
A pointer to a thread pump interface (see ID3DX10ThreadPump Interface). Use NULL to specify that this function should not return until it is completed.
-
ppShader [out]
-
Type: ID3D10Blob**
A pointer to an ID3D10Blob Interface which contains the compiled shader, as well as any embedded debug and symbol-table information.
-
ppErrorMsgs [out]
-
Type: ID3D10Blob**
A pointer to an ID3D10Blob Interface which contains a listing of errors and warnings that occurred during compilation. These errors and warnings are identical to the debug output from a debugger.
-
pHResult [out]
-
Type: HRESULT*
A pointer to the return value. May be NULL. If pPump is not NULL, then pHResult must be a valid memory location until the asynchronous execution completes.
Return value
Type: HRESULT
The return value is one of the values listed in Direct3D 10 Return Codes.
