#include <utilmm/system/system.hh>
The C++ guard mechanism applied to file descriptors: when destroyed, an auto_close object releases the file descriptor it has been given at construction.
◆ auto_close() [1/3]

◆ auto_close() [2/3]
| utilmm::auto_close::auto_close |

◆ auto_close() [3/3]
| utilmm::auto_close::auto_close |

◆ ~auto_close()
| utilmm::auto_close::~auto_close |
( |

|
◆ close()
| void utilmm::auto_close::close |
( |
| ) |
|
Close the file descriptor right away
◆ detach()
| void utilmm::auto_close::detach |
( |
| ) |
|
Disassociates this object and the file descriptor associated with it without closing the file descriptor
◆ handle() [1/3]
template<typename T >
| T utilmm::auto_close::handle |
( |
| ) |
const |
Access to the file descriptor.
- Exceptions
-
| std::bad_cast | Raised if the required type is not the right file descriptor type (i.e. if handle<FILE> is calledd on a auto_close object created with an 'int' fd) |
◆ handle() [2/3]
template<>
| FILE* utilmm::auto_close::handle |
( |
| ) |

◆ handle() [3/3]
template<>
| int utilmm::auto_close::handle |

◆ reset() [1/2]
| void utilmm::auto_close::reset |
( |
int |
fd | ) |
|
First, close the current defined file descriptor and then sets it to a new one. Calling reset(-1) is equivalent to calling close() directly.
◆ reset() [2/2]
| void utilmm::auto_close::reset |
( |
FILE * |
stream | ) |
|
First, close the current defined file descriptor and then sets it to a new one. Calling reset(-1) is equivalent to calling close() directly.
