fts::ffi::fts_open

pub unsafe extern fn fts_open(path_argv: *const *const c_char, options: c_int, compar: Option< extern "C" fn(*const *const FTSENT, *const *const FTSENT) -> c_int>) -> *mut FTS

fts_open() in fts.h

C function

FTS *fts_open(char * const *path_argv, int options, 
              int (*compar)(const FTSENT **, const FTSENT **));

Safety

path_argv must be a pointer of a null-terminated array of C strings( null-terminated ).

options must contain either FTS_LOGICAL or FTS_PHYSICAL.

Examples

let path  = std::ffi::CString::new( "." ).unwrap().as_ptr();
let paths = vec![path, std::ptr::null()];
let _fts  = unsafe { fts::ffi::fts_open( paths.as_ptr(), fts::ffi::FTS_LOGICAL, None ) };
