# insertGlyphs(_:length:forStartingGlyphAt:characterIndex:)

Inserts the given glyphs into the glyph cache at the given index and maps them to characters beginning at the given character index.

## Declaration

```swift
func insertGlyphs(_ glyphs: UnsafePointer<NSGlyph>, length: Int, forStartingGlyphAt glyphIndex: Int, characterIndex charIndex: Int)
```

## Parameters

- `glyphs`: The glyphs to insert.
- `length`: The number of glyphs to insert.
- `glyphIndex`: The index in the glyph cache to begin inserting glyphs.
- `charIndex`: Index of first character to be mapped.

## Discussion

Discussion This method is part of the NSGlyphStorage protocol, for use by the glyph generator. It enables bulk insertion of glyphs into the glyph cache.
