curl error trapping in ksh

I hope that I can trap curl errors, and have my shell script error out and quit if curl has any sort of problem.

For example, I have the following command in my shell script:

Code:
 curl --trace -n -v --ftp-ssl ftp://xxx.xxx.xxx.xxx:2122 --user user:password -o /tmp/file.txt

Works great, except for sometimes when we have a network problem or something, and I get:

curl: (56) FTP response reading failed

So I get a good error message, but I want my whole script to send an error signal if this occurs.

In other words, I'd like the script to send a signal similar to what would occur with an 'exit 1' to the OS. I can do this with an error trapping function, but does curl have a flag or something for signaling so I don't have to write a function?

OR perhaps am I not understanding what I need to detect an error and signal?

Thank you for your time and understanding.

CURLOPT_INFILESIZE_LARGE(3)				     curl_easy_setopt options				       CURLOPT_INFILESIZE_LARGE(3)

NAME
CURLOPT_INFILESIZE_LARGE - set size of the input file to send off SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INFILESIZE_LARGE, curl_off_t filesize); DESCRIPTION
When uploading a file to a remote site, filesize should be used to tell libcurl what the expected size of the input file is. This value must be passed as a curl_off_t. For uploading using SCP, this option or CURLOPT_INFILESIZE(3) is mandatory. To unset this value again, set it to -1. When sending emails using SMTP, this command can be used to specify the optional SIZE parameter for the MAIL FROM command. This option does not limit how much data libcurl will actually send, as that is controlled entirely by what the read callback returns, but telling one value and sending a different amount may lead to errors. DEFAULT
Unset PROTOCOLS
Many EXAMPLE
CURL *curl = curl_easy_init(); if(curl) { curl_off_t uploadsize = FILE_SIZE; curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/destination.tar.gz"); curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L); curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, uploadsize); curl_easy_perform(curl); } AVAILABILITY
SMTP support added in 7.23.0 RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. SEE ALSO
CURLOPT_INFILESIZE(3), CURLOPT_UPLOAD(3), libcurl 7.54.0 February 03, 2016 CURLOPT_INFILESIZE_LARGE(3)
