binfile
fl=new("binfile"[,filename$])
The binfile object provides read/write access to the file in binary fashion, where there is no concept of a record. All access is to specific byte positions in the file, or the file as a whole. The filename$ argument specifies what file to open or create. If no file name is supplied, then a temporary file will be created. This temporary file will be erased when the UnForm job is complete.
Properties
filename$ is a read-only property that contains the full path to the file name opened or created.
|
size contains the file size in bytes. If size is assigned, the file is expanded or truncated to the specified size.
|
Methods
append(block$) appends block$ to the end of the file, and returns the size of the file.
|
delblock(index,length) removes the specific bytes from the file, and returns the size of the file.
|
getblock$(index,length) returns file content at the specified position and length. The position is 1-based, so the first byte is 1.
|
getfile$() returns the entire contents of the file.
|
insblock(index,block$) inserts block$ in the file at the 1-based index position. Returns the size of the file.
|
purge() sets the file length to 0, just like setting the size property to 0.
|
putblock(index,block$) writes block$ to the file at the 1-based index position, replacing data at that position. Returns the size of the file.
|
putfile(block$) updates the file contents to block$, truncating or expanding as necessary. Returns the size of the file.
