#[unsafe(no_mangle)]
pub unsafe extern "C" fn patch_seq_file_slurp_safe(
    stack: Stack,
) -> Stack
Expand description

Read entire file contents as a string, with error handling

Stack effect: ( String – String Int )

Takes a file path, attempts to read the entire file. Returns (contents 1) on success, or (“” 0) on failure. Failure cases: file not found, permission denied, not valid UTF-8, etc.

§Safety

  • stack must be a valid, non-null stack pointer with a String value on top
  • Caller must ensure stack is not concurrently modified
