Preprocess a set of header files found under dir

Source: R/parse-headers.R
preprocess_headers.Rd

This helper calls preprocess_header() for each matching file in dir and returns a named list with the path as the keys and the preprocessed text as the values.

Usage

preprocess_headers(
  dir = R.home("include"),
  recursive = TRUE,
  pattern = c("\\.h$", "\\.H$"),
  cc = r_cc(),
  ccflags = NULL,
  ...
)

Logical; whether to search recursively.
