tcc_treesitter_union_accessors: Generate tcc_union() accessors from header unions

In Rtinycc: Builds the 'TinyCC' Command-Line Interface and Library for 'C' Scripting in 'R'

Generate tcc_union() accessors from header unions

Description

Generate tcc_union() accessors from header unions

Usage

tcc_treesitter_union_accessors(
  header,
  mapper = tcc_map_c_type_to_ffi,
  bitfield_type = "u8",
  include_bitfields = TRUE
)

Arguments

header	Character scalar containing C declarations.
mapper	Function to map C types to FFI types.
bitfield_type	FFI type to use for bitfields.
include_bitfields	Whether to include bitfields.

Value

Named list of accessors by union name. Bitfields are returned as lists with type, bitfield = TRUE, and width. Nested struct members are returned as ⁠list(type = "struct", struct_name = <name>)⁠ when the struct name is available, otherwise list(type = "struct").

Examples

## Not run: 
header <- "union data { int i; double d; };"
tcc_treesitter_union_accessors(header)

## End(Not run)
