2.4 Argument Conversion

The bulk of Guile-GI is the code that converts Scheme function arguments to and from from the native arguments and return values that a library expects. Guile-GI tries to do it in a predictable and unsurprising way, but, the conversion from Scheme to native types has some mismatch.

• Function Parameters, Arity, and Return Values
• Booleans
• Characters
• Numbers
• Strings
• Structs, Unions, and Objects
• Native Pointers
• Arrays
• Null Pointers and Optional Arguments
• Hash Tables and GHashTable Types
