fitsio-sys 0.1.4

FFI wrapper around cfitsio
Documentation

This package was automatically generated with rust-bindgen and as such was not user-generated.

The functions contained are expected to be used with fitsio, a high level API wrapper around the low level direct C-bindings, though the bindings are complete enough to be usable.

This code will not be directly documented, and so users should refer to the fitsio C documentation for usage.

Note about function names

Unfortunately we must use fits short names throughout. The C-api exposes long names for functions which are more descriptive, for example fits_open_file instead of ffopen, but the symbols available in the library have only short names, and the long names are merely preprocessor definitions.

Examples

# extern crate fitsio_sys;
use std::ptr;
use std::ffi;
# use fitsio_sys::{ffinit, ffphps, ffclos};

# fn main() {
let filename = ffi::CString::new("!/tmp/test.fits").unwrap();
let mut fptr = ptr::null_mut();
let mut status = 0;

unsafe {
    // Create a new file, clobbering any pre-existing file
    ffinit(&mut fptr as *mut *mut _,
        filename.as_ptr(),
        &mut status);

    // Add an empty primary HDU
    ffphps(fptr, 8, 0, ptr::null_mut(), &mut status);

    // Finally close the file
    ffclos(fptr, &mut status);
}

assert_eq!(status, 0);
# }
