ElfImage Class

Namespace: GHIElectronics.TinyCLR.RuntimeLoadableProcedures · Assembly: GHIElectronics.TinyCLR.RuntimeLoadableProcedures

A loaded ELF binary. Construct with the ELF bytes, look up symbols by name, then build a NativeFunction from a function-symbol's address to call it.

public sealed class ElfImage : IDisposable

Constructors

ElfImage(byte[] elfImageData)

public ElfImage(byte[] elfImageData)

Loads an ELF image into device memory.

Parameter	Type	Description
elfImageData	byte[]	ELF binary bytes.

Properties

Size

public uint Size { get; }

Total size of the loaded image.

RegionCount

public uint RegionCount { get; }

Number of distinct ELF regions loaded.

Methods

Dispose()

public void Dispose()

Unloads the image from device memory.

FindSymbolAddress(string name, SymbolType type)

public uint FindSymbolAddress(string name, SymbolType type)

Looks up a symbol by name and type.

Parameter	Type	Description
name	string	Symbol name.
type	SymbolType	Symbol classification.

Returns uint — Symbol's runtime address, or 0 if not found.

FindFunction(string name)

public NativeFunction FindFunction(string name)

Locates a function symbol and wraps it in a NativeFunction.

Parameter	Type	Description
name	string

Returns NativeFunction

InitializeBssRegion()

public void InitializeBssRegion()

Zero-initializes the loaded image's BSS region using the standard __bss_start__/__bss_end__ symbols.

InitializeBssRegion(string startSymbolName, string endSymbolName)

public void InitializeBssRegion(string startSymbolName, string endSymbolName)

Zero-initializes the region delimited by two symbols.

Parameter	Type	Description
startSymbolName	string	Symbol marking the start of the region.
endSymbolName	string	Symbol marking the end of the region.

ZeroRegion(uint address, uint length)

public void ZeroRegion(uint address, uint length)

Zero-fills a span of length bytes starting at address.

Parameter	Type	Description
address	uint
length	uint
