Description

Use the CC_ERROR function to get a pointer to the “canned” error

message corresponding to an error number. This error number is typically

the value of the iostat variable or the return status of an API function. We

recommend that you use this function in a C routine, although you can use

it in a BASIC procedure. See CC_ERRSTR for a BASIC procedure.
