createTempElfFile

fnstring createTempElfFile(const(ubyte)[] data, string prefix = "elftest")

Create a temporary ELF file with the given data.

This function creates an exclusively-owned temporary directory in the system's temp directory (directory creation is an atomic exclusive operation, which also defeats symlink pre-placement attacks), writes the provided data to a .elf file inside it, and returns the file path.

Parameters

`data`	The byte data to write to the temporary ELF file.
`prefix`	Optional prefix for the temporary directory name (default: "elftest").

Returns

The full path to the created temporary file.

Throws

Exception if the temporary directory or file cannot be created.

Examples

ubyte[] elfData = [0x7f, 'E', 'L', 'F', ...];
string tempPath = createTempElfFile(elfData);
scope (exit) cleanupTempFile(tempPath);
// Use tempPath in tests
