B-21

Copies the “canned” null-terminated error message into the user’s

local buffer.

C Syntax

#include <copro.h>

void CC_ERRSTR (error,err_ptr)

unsigned error;

unsigned char *err_ptr;

Parameters

error

Specifies which error message to copy. The number is typically

supplied by the status returned from an API function call or the I/O

status returned in iostat.

err_ptr

This parameter specifies an 80-character buffer to which the error string

will be copied

Returns

None.

Description

Use the CC_ERRSTR function to copy the “canned” error message

corresponding to an error number into the user’s local buffer. 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 BASIC

procedure, although you can use it in a C routine. See CC_ERROR for a

C routine.
