WriteFileAsHex()

WriteFileAsHex(filePath: string, data: string, offset: number, whence: number): respBase;

Writes the provided base-16 (hexadecimal) encoded data to the filePath file in the VFS, starting at the specified offset computed from whence. The file is treated as binary data.

Parameters

Parameter	Type	Explanation
filePath	string	The fully qualified, root-based, POSIX path to the file in the VFS
data	string	The string of hex-encoded bytes to write to the file
offset	number	The positional offset, computed from whence, where the write operation will begin
whence	number	One of: FromStart, FromEnd

NOTE

offset and whence together determine where writing begins. 0,FromStart overwrites the file from the beginning; 0,FromEnd appends new data to the file.

Example

var vfs = GetCurrentVFS();
if (vfs != null) {
    var resp = vfs.WriteFileAsHex("/data/archive.dat", "FFD8", 0, FromEnd);
    if (resp.Ok()) {
        Log("Data written"); // Bytes 255 (FF) and 216 (D8) appended to file
    } else {
        Log("Error: " + resp.ErrorMsg());
    }
} else {
    Log("VFS was null");
}
