Syntax

public static class NVRTCNativeMethods

Methods

nvrtcAddNameExpression(nvrtcProgram, String)

nvrtcAddNameExpression notes the given name expression denoting a global function or function template instantiation.

The identical name expression string must be provided on a subsequent call to nvrtcGetLoweredName to extract the lowered name.

Declaration

public static nvrtcResult nvrtcAddNameExpression(nvrtcProgram prog, string name_expression)

Parameters

Type	Name	Description
nvrtcProgram	prog	CUDA Runtime Compilation program.
System.String	name_expression	constant expression denoting a global function or function template instantiation.

Returns

Type	Description
nvrtcResult

nvrtcCompileProgram(nvrtcProgram, Int32, IntPtr[])

compiles the given program.

Declaration

public static nvrtcResult nvrtcCompileProgram(nvrtcProgram prog, int numOptions, IntPtr[] options)

Parameters

Type	Name	Description
nvrtcProgram	prog	CUDA Runtime Compiler program.
System.Int32	numOptions	Number of compiler options passed.
System.IntPtr[]	options	Compiler options in the form of C string array. options can be NULL when numOptions is 0.

Returns

Type	Description
nvrtcResult

nvrtcCreateProgram(ref nvrtcProgram, String, String, Int32, IntPtr[], IntPtr[])

creates an instance of ::nvrtcProgram with the given input parameters, and sets the output parameter \p prog with it.

Declaration

public static nvrtcResult nvrtcCreateProgram(ref nvrtcProgram prog, string src, string name, int numHeaders, IntPtr[] headers, IntPtr[] includeNames)

Parameters

Type	Name	Description
nvrtcProgram	prog	CUDA Runtime Compiler program.
System.String	src	CUDA program source.
System.String	name	CUDA program name. name can be NULL; "default_program" is used when name is NULL.
System.Int32	numHeaders	Number of headers used. numHeaders must be greater than or equal to 0.
System.IntPtr[]	headers	Sources of the headers. headers can be NULL when numHeaders is 0.
System.IntPtr[]	includeNames	Name of each header by which they can be included in the CUDA program source. includeNames can be NULL when numHeaders is 0.

Returns

Type	Description
nvrtcResult

nvrtcDestroyProgram(ref nvrtcProgram)

destroys the given program.

Declaration

public static nvrtcResult nvrtcDestroyProgram(ref nvrtcProgram prog)

Parameters

Type	Name	Description
nvrtcProgram	prog	CUDA Runtime Compiler program.

Returns

Type	Description
nvrtcResult

nvrtcGetErrorString(nvrtcResult)

helper function that stringifies the given #nvrtcResult code, e.g., NVRTC_SUCCESS to "NVRTC_SUCCESS". For unrecognized enumeration values, it returns "NVRTC_ERROR unknown"

Declaration

public static string nvrtcGetErrorString(nvrtcResult result)

Parameters

Type	Name	Description
nvrtcResult	result	CUDA Runtime Compiler API result code.

Returns

Type	Description
System.String	Message string for the given nvrtcResult code.

nvrtcGetLoweredName(nvrtcProgram, String, ref IntPtr)

nvrtcGetLoweredName extracts the lowered (mangled) name for a global function or function template instantiation, and updates *lowered_name to point to it. The memory containing the name is released when the NVRTC program is destroyed by nvrtcDestroyProgram.

The identical name expression must have been previously provided to nvrtcAddNameExpression.

Declaration

public static nvrtcResult nvrtcGetLoweredName(nvrtcProgram prog, string name_expression, ref IntPtr lowered_name)

Parameters

Type	Name	Description
nvrtcProgram	prog	CUDA Runtime Compilation program.
System.String	name_expression	constant expression denoting a global function or function template instantiation.
System.IntPtr	lowered_name	initialized by the function to point to a C string containing the lowered (mangled) name corresponding to the provided name expression.

Returns

Type	Description
nvrtcResult

nvrtcGetProgramLog(nvrtcProgram, Byte[])

stores the log generated by the previous compilation of prog in the memory pointed by log.

Declaration

public static nvrtcResult nvrtcGetProgramLog(nvrtcProgram prog, byte[] log)

Parameters

Type	Name	Description
nvrtcProgram	prog	CUDA Runtime Compiler program.
System.Byte[]	log	Compilation log.

Returns

Type	Description
nvrtcResult

nvrtcGetProgramLogSize(nvrtcProgram, ref SizeT)

sets logSizeRet with the size of the log generated by the previous compilation of prog (including the trailing NULL).

Declaration

public static nvrtcResult nvrtcGetProgramLogSize(nvrtcProgram prog, ref SizeT logSizeRet)

Parameters

Type	Name	Description
nvrtcProgram	prog	CUDA Runtime Compiler program.
SizeT	logSizeRet	Size of the compilation log (including the trailing NULL).

Returns

Type	Description
nvrtcResult

nvrtcGetPTX(nvrtcProgram, Byte[])

stores the PTX generated by the previous compilation of prog in the memory pointed by ptx.

Declaration

Parameters

Type	Name	Description
nvrtcProgram	prog	CUDA Runtime Compiler program.
System.Byte[]	ptx	Compiled result.

Returns

Type	Description
nvrtcResult
