Arguments

Returns

t if the named file exists and is busy, otherwise nil.

Description

This function is supported only by certain operating system and hardware combinations that mark files as busy when they are opened for write by another task. You can check this using the ls -l shell command. If it shows a busy file with a 'B' or 'b' as the first bit in the bitmask, this function should be supported.

Example

Gamma> is_busy("/tmp/busyfile");
t
