: Create a new empty file with a unique name.
uniq-file [ define ] <file name> [ temporary ]
One of the common tasks in many applications is creating a unique file (of any kind, including temporary). uniq-file statement does that - it creates a new unique file of zero size, with <file name> being its fully qualified name, which is always within the file_storage
. <file name> is allocated memory
If string variable <file name> does not exist, it can be created with "define" clause. The file itself is created empty. If "temporary" clause is used, then the file created is a temporary_file
The file has no extension. You can rename it after it has been created to reflect its usage or purpose.
All files created are setup with owner and group read/write only permissions.
The following creates an empty file with auto-generated name that will be stored in "mydoc" variable. String variable "mydoc" is defined in the statement. The string "some data" is written to a newly created file:
uniq-file define mydoc
write-file mydoc from "some data"
To create a temporary file:
uniq-file define temp_file temporary
( close-file copy-file delete-file file-position file_storage file_uploading lock-file open-file read-file read-line rename-file stat-file temporary_file uniq-file unlock-file write-file
