Syntax

public static class MarshalTk

Methods

FreeAnsiStringArrayPtr(byte**, uint)

Frees unmanaged ansi string arrays allocated by MarshalStringArrayToAnsiStringArrayPtr(ReadOnlySpan<string>, out uint).

Declaration

public static void FreeAnsiStringArrayPtr(byte** strArrayPtr, uint count)

Parameters

Type	Name	Description
byte**	strArrayPtr	The unmanaged ansi string array.
uint	count	The number of strings in the array.

FreeStringArrayPtr(nint, int)

Frees a marshaled string that allocated by MarshalStringArrayToPtr.

Declaration

public static void FreeStringArrayPtr(nint ptr, int length)

Parameters

Type	Name	Description
nint	ptr	An unmanaged pointer allocated with MarshalStringArrayToPtr.
int	length	The length of the string array.

FreeStringPtr(nint)

Frees a marshaled string that allocated by MarshalStringToPtr.

Declaration

public static void FreeStringPtr(nint ptr)

Parameters

Type	Name	Description
nint	ptr	An unmanaged pointer allocated with MarshalStringToPtr.

MarshalAnsiStringArrayPtrToStringArray(byte**, uint)

Marshals a byte** ansi string array into a string[].

Declaration

public static string[] MarshalAnsiStringArrayPtrToStringArray(byte** strArrayPtr, uint length)

Parameters

Type	Name	Description
byte**	strArrayPtr	The ansi string array pointer.
uint	length	The number of strings in the array.

Returns

Type	Description
string[]	The managed string array.

MarshalPtrToString(nint)

Marshals a pointer to a null-terminated byte array to a new System.String. This method supports OpenTK and is not intended to be called by user code.

Declaration

public static string MarshalPtrToString(nint ptr)

Parameters

Type	Name	Description
nint	ptr	A pointer to a null-terminated byte array.

Returns

Type	Description
string	A System.String with the data from ptr.

MarshalStringArrayToAnsiStringArrayPtr(ReadOnlySpan<string>, out uint)

Converts a span of strings into an unmanged ansi string array. Use FreeAnsiStringArrayPtr(byte**, uint) to free the array.

Declaration

public static byte** MarshalStringArrayToAnsiStringArrayPtr(ReadOnlySpan<string> stringArray, out uint count)

Parameters

Type	Name	Description
ReadOnlySpan<string>	stringArray	The span of strings to marshal.
uint	count	The number of strings in the unmanged array. The same as the length of the array.

Returns

Type	Description
byte**	The unmanaged ansi string array.

MarshalStringArrayToPtr(string[])

Marshals a System.String array to unmanaged memory by calling Marshal.AllocHGlobal for each element.

Declaration

public static nint MarshalStringArrayToPtr(string[] strArray)

Parameters

Type	Name	Description
string[]	strArray	The string array to marshal.

Returns

Type	Description
nint	An unmanaged pointer to an array of null-terminated strings.

MarshalStringToPtr(string)

Marshal a System.String to unmanaged memory. The resulting string is encoded in UTF8 and must be freed with FreeStringPtr.

Declaration

public static nint MarshalStringToPtr(string str)

Parameters

Type	Name	Description
string	str	The System.String to marshal.

Returns

Type	Description
nint	An unmanaged pointer containing the marshaled string. This pointer must be freed with FreeStringPtr.
