An operation tried to write to memory that is read-only.


In Julia, the ReadOnlyMemoryError() function is used to create an error object representing a memory write attempt on read-only memory. This error is raised when an operation tries to modify memory that is designated as read-only. Here are some examples of its usage:

  1. Throw a read-only memory error:

    julia> error(ReadOnlyMemoryError())
    ERROR: ReadOnlyMemoryError()
    [1] top-level scope
      @ REPL[1]:1

    This example demonstrates how to explicitly raise a ReadOnlyMemoryError. It will generate an error message indicating a write attempt on read-only memory.

  2. Handle a read-only memory error using a try-catch block:

    julia> try
              # Code that tries to write to read-only memory
          catch err
              println("Error occurred: ", err)
    Error occurred: ReadOnlyMemoryError()

    This example shows how to catch a ReadOnlyMemoryError using a try-catch block. The catch block handles the error by printing a custom message.

Remember that the ReadOnlyMemoryError() function is typically used to indicate an illegal attempt to write to read-only memory.
