NAME
Filesys::POSIX::FdTable - File descriptor table
DESCRIPTION
This internal module used by Filesys::POSIX handles the allocation and tracking of numeric file descriptors associated with inodes opened for I/O. It does not intend to expose any public interfaces.
METHODS
Filesys::POSIX::FdTable->new-
Create a new file descriptor table object. Returns a blessed hash.
$fd_table->open($inode, $flags)-
Asks the
$inodeobject to open and return a Filesys::POSIX::IO::Handle object. Accepts flags as defined in Filesys::POSIX::Bits. A reference to the inode, file handle, flags passed will be stored.Returns a unused file descriptor number greater than 2, unique to the current file descriptor table, upon success. Possible exceptions may be thrown:
ENODEV (No such device or address)
Could not open a file handle for the inode passed.
$fd_table->lookup($fd)-
Given a file descriptor number, return the file descriptor table entry stored; such an object contains an inode reference, a file handle reference, and the flags with which the file was opened. Possible exceptions include:
EBADF (Bad file descriptor)
No handle found for the given file descriptor.
$fd_table->close($fd)-
Close the file handle corresponding to the given file descriptor, and remove the file descriptor from the table, freeing it for future reallocation.
$fd_table->list-
Return a list of all file descriptor numbers currently allocated.
