Generate tcc_union() accessors from header unions

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

if (FALSE) { # \dontrun{
header <- "union data { int i; double d; };"
tcc_treesitter_union_accessors(header)
} # }
