Delimited by a chr(255)

[James Prato]

In C, how do you read data fields from a file that are separated/delimited
by a chr(255)?

For example, Field1chr(255)Field2chr(255), etc where Fieldx could be NULL.

You could read characters with fgetc() until you encounter a
character with value 255. (In C, we don't use your "chr"
notation; perhaps you are more familiar with Pascal or Perl than
with C.)

Have you tried writing code to do this? What difficulties did
you encounter? It is quite straightforward.

The question is unclear to me. Did you meant Field1 and Field2 are
character buffers of size of 255 or you meant the strings are seperated
by ascii character 255?

Neither. He didn't mention ASCII, and he didn't mention buffer sizes.

He is trying to tokenise on a given character, that's all. The solution is a
simple getc loop.
