IniWrite, Pairs, Filename, Section

Pairs - The complete content of a section to write to the .ini file, excluding the [SectionName] header. Key must be omitted. Pairs must not contain any blank lines. If the section already exists, everything up to the last key=value pair is overwritten. Pairs can contain lines without an equal sign (=), but this may produce inconsistent results.
