CFilePtr

starnix_c_file_buffer

Struct CFilePtr 

Source 
pub struct CFilePtr<'a> { /* private fields */ }
Expand description

A wrapper around the raw FILE* that borrows CFileBuffer mutably. This ensures exclusive access to the file descriptor.

Implementations§

Source§

impl<'a> CFilePtr<'a>

Source

pub fn as_raw(&self) -> *mut FILE

Get the raw FILE* pointer.

§Safety Constraints

The returned raw pointer must not be stored or used after this CFilePtr (or the parent CFileBuffer) is dropped. The caller must ensure that the parent CFileBuffer outlives any use of the raw pointer.
