<p><b>int open(const string &amp;in filename, const string &amp;in mode)</b><br />
</p>
<p>Opens a file. The mode can be "r" for reading, "w" for writing, or "a" for appending.</p>
<p>If the file couldn't be opened, a negative value is returned.</p>
<p><b>int close()</b><br />
</p>
<p>Closes the file.</p>
<p>If no file is open, a negative value is returned.</p>
<p><b>int getSize() const</b><br />
</p>
<p>Returns the size of the file, or a negative value if no file is open.</p>
<p><b>bool isEndOfFile() const</b><br />
</p>
<p>Returns true if the current position is at the end of the file.</p>
<p><b>string readString(uint length)</b><br />
</p>
<p>Reads <em>length</em> bytes into a string and returns it.</p>
<p><b>string readLine()</b><br />
</p>
<p>Reads until a new line character, e.g. '\n', or end-of-file and returns the string. The new line character is also returned in the string.</p>
<p><b>int64 readInt(uint bytes)</b><br />
</p>
<p>Reads <em>bytes</em> as a signed integer number.</p>
<p><b>uint64 readUInt(uint bytes)</b><br />
</p>
<p>Reads <em>bytes</em> as an unsigned integer number.</p>
<p><b>float readFloat()</b><br />
</p>
<p>Reads 4 bytes as a float number.</p>
<p><b>double readDouble()</b><br />
</p>
<p>Reads 8 bytes as a double number.</p>
<p><b>int writeString(const string &amp;in str)</b><br />
</p>
<p>Writes the bytes of the string into the file.</p>
<p>Returns the number of bytes written, or a negative value on error.</p>
<p><b>int writeInt(int64 value, uint bytes)</b><br />
</p>
<p>Writes <em>bytes</em> as a signed integer value.</p>
<p>Returns the number of bytes written, or a negative value on error.</p>
<p><b>int writeUInt(uint64 value, uint bytes)</b><br />
</p>
<p>Writes <em>bytes</em> as an unsigned integer value.</p>
<p>Returns the number of bytes written, or a negative value on error.</p>
<p><b>int writeFloat(float value)</b><br />
</p>
<p>Writes 4 bytes as a float value.</p>
<p>Returns the number of bytes written, or a negative value on error.</p>
<p><b>int writeDouble(double value)</b><br />
</p>
<p>Writes 8 bytes as a double value.</p>
<p>Returns the number of bytes written, or a negative value on error.</p>
<p><b>int getPos() const</b><br />
</p>
<p>Returns the current position in the file, or a negative value on error.</p>
<p><b>int setPos(int pos)</b><br />
</p>
<p>Sets the current position in the file. Returns the previous position or a negative value on error.</p>
<p><b>int movePos(int delta)</b><br />
</p>
<p>Moves the position <em>delta</em> bytes relative to the current position. Returns the previous position or a negative value on error.</p>
<h2><a class="anchor" id="doc_script_stdlib_file_1_2"></a>
Properties</h2>
<p><b>bool mostSignificantByteFirst</b><br />
</p>
<p>This property should be set to true if the most significant bit should be read or written first in the methods that reads/writes numbers.</p>
<p>It is set to false by default, which is the standard on most platforms. </p>
