Member Function Documentation

void auto_close::close

(

)

Close the file descriptor right away

Definition at line 48 of file system.cc.

void auto_close::detach

(

)

Disassociates this object and the file descriptor associated with it without closing the file descriptor

Definition at line 62 of file system.cc.

int utilmm::auto_close::handle< int >

(

)

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)

Definition at line 66 of file system.cc.

void 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.

Definition at line 79 of file system.cc.

void 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.
