resource +lock <lockname>

Return: Always "", errors are fatal

---

resource -unlock <lockname>

Return: Always "", errors are fatal

---


Locking allows multiple threads to access same resource (file/environmental variable) with thread safe means.

-- Example use --

filereader.itcl:

resource +lock $filename
set data [gets $fchannel]
resource -unlock $filename

filewriter.itcl:

resource +lock $filename
puts $fchannel $data
resource -unlock $filename

resource +share channel <shareName> <channelName>

Return: "" on success, error is fatal

---

resource -unshare channel <shareName>

Return: ChannelName on success, error is fatal

---


Use this with locks, to create persistent connections, like:


iputs -nobuffer "Locking and Sharing juliet"

resource +lock "juliet"

if { [catch { set juliet [resource -unshare channel "juliet www server"] }] != 0 }

iputs -nobuffer "Creating juliet"

set juliet [socket www.inet.fi 80]

} else {
iputs -nobuffer "Juliet read from share"
}

iputs -nobuffer "Sharing juliet: $juliet"

resource +share channel "juliet www server" $juliet

resource -unlock "juliet"

iputs -nobuffer "Juliet successfully processed"


*Note* After sharing channel, interpreter does not have control anymore - read/write/etc will return with fatal error.

Question iTCL vfs command...?

Please d1 what are all commands of iTCL vfs?

I found:

vfs delete <directory/file> <path>
vfs write <directory/file> <path> <Uid> <Gid> <Mode>
vfs chattr <directory/file> <path> <1/??> <vlink>
