Struct shadow_rs::host::descriptor::LegacyFileCounter

source ·
pub struct LegacyFileCounter { /* private fields */ }
Expand description

Used to track how many descriptors are open for a LegacyFile.

When the close() method is called, the legacy file’s legacyfile_close() will only be called if this is the last descriptor for that legacy file. This is similar to an OpenFile object, but for C files.

Implementations§

source§

impl LegacyFileCounter

source

pub fn new(file: CountedLegacyFileRef) -> Self

source

pub fn ptr(&self) -> *mut LegacyFile

source

pub fn close(self, host: &Host)

Close the descriptor, and if this is the last descriptor pointing to its legacy file, close the legacy file as well.
