Declared in <bdls_filedescriptorguard.h>
struct FileDescriptorGuard;| Name | Description |
|---|---|
FileDescriptorGuard [constructor] | Create a guard object that will manage the specified descriptor, closing it upon destruction (unless either realease or closeAndRelease has been called). It is permissible for descriptor to be FilesystemUtil::k_INVALID_FD, in which case the guard created will not manage anything. |
~FileDescriptorGuard [destructor] | If this guard object manages a file, close that file. |
closeAndRelease | Close the file managed by this guard and release that file from management by this object. The behavior is undefined unless this object is managing a file. |
descriptor | If this guard is managing a file, return the file descriptor referring to that file, and return FilesystemUtil::k_INVALID_FD otherwise. |
release | Release the file from management by this object (without closing it) and return the formerly managed descriptor. The behavior is undefined unless this object is managing a file. |
