Uso del SysUtils.FileWrite. ¿Cómo?

[[escafandra]]

No se trata de una función de la API de Windows si no una función de delphi:

Writes the contents of a buffer to the current position in a file.

Unit

SysUtils

Category

file management routines

Delphi syntax:

function FileWrite(Handle: Integer; const Buffer; Count: Integer): Integer;

C++ syntax:

extern PACKAGE int __fastcall FileWrite(int Handle, const void *Buffer, unsigned Count);

Description

FileWrite writes Count bytes to the file given by Handle from the buffer specified by Buffer. Handle is a file handle returned by the FileOpen or FileCreate method.

The return value is the number of bytes actually written, or -1 if an error occurred.

: Do not mix routines that take or return file handles with those that use Delphi language file variables (typically seen as var F). To write to a file specified by a Delphi file variable, use Write, Writeln, or BlockWrite instead.

Saludos.
