.SH NAME

|
|
.SH SYNOPSIS
|
|
.nf

|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_LOCAL_IP, char **ip);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a pointer to a char pointer to receive the pointer to a null\-terminated
|
|
string holding the IP address of the local end of most recent connection done
|
|
with this \fBcurl\fP handle. This string may be IPv6 when that is
|
|
enabled. Note that you get a pointer to a memory area that is reused at next
|
|
request so you need to copy the string if you want to keep the information.
|
|
|
|
The \fBip\fP pointer is NULL or points to private memory. You MUST NOT free \-
|
|
it gets freed when you call \fIcurl_easy_cleanup(3)\fP on the corresponding
|
|
CURL handle.
