.TH curl_easy_getinfo 3 "20 Aug 2003" "libcurl 7.10.8" "libcurl Manual"
|
|
.SH NAME
|
|
curl_easy_getinfo - extract information from a curl handle
|
|
.SH SYNOPSIS
|
|
.B #include <curl/curl.h>
|
|
|
|
.B "CURLcode curl_easy_getinfo(CURL *curl, CURLINFO info, ... );"
|
|
|
|
.SH DESCRIPTION
|
|
Request internal information from the curl session with this function. The
|
|
third argument
|
|
.B MUST
|
|
be a pointer to a long, a pointer to a char * or a pointer to a double (as
|
|
this documentation describes further down). The data pointed-to will be
|
|
filled in accordingly and can be relied upon only if the function returns
|
|
CURLE_OK. This function is intended to get used *AFTER* a performed transfer,
|
|
all results from this function are undefined until the transfer is completed.
|
|
.SH AVAILABLE INFORMATION
|
|
These are informations that can be extracted:
|
|
.IP CURLINFO_EFFECTIVE_URL
|
|
Pass a pointer to a 'char *' to receive the last used effective URL.
|
|
.IP CURLINFO_RESPONSE_CODE
|
|
Pass a pointer to a long to receive the last received HTTP or FTP code. This
|
|
option was known as CURLINFO_HTTP_CODE in libcurl 7.10.7 and earlier.
|
|
.IP CURLINFO_FILETIME
|
|
Pass a pointer to a long to receive the remote time of the retrieved
|
|
document. If you get -1, it can be because of many reasons (unknown, the
|
|
server hides it or the server doesn't support the command that tells document
|
|
time etc) and the time of the document is unknown. Note that you must tell the
|
|
server to collect this information before the transfer is made, by using the
|
|
CURLOPT_FILETIME option to \fIcurl_easy_setopt(3)\fP. (Added in 7.5)
|
|
.IP CURLINFO_TOTAL_TIME
|
|
Pass a pointer to a double to receive the total transaction time in seconds
|
|
for the previous transfer. This time does not include the connect time, so if
|
|
you want the complete operation time, you should add the
|
|
CURLINFO_CONNECT_TIME.
|
|
.IP CURLINFO_NAMELOOKUP_TIME
|
|
Pass a pointer to a double to receive the time, in seconds, it took from the
|
|
start until the name resolving was completed.
|
|
.IP CURLINFO_CONNECT_TIME
|
|
Pass a pointer to a double to receive the time, in seconds, it took from the
|
|
start until the connect to the remote host (or proxy) was completed.
|
|
.IP CURLINFO_PRETRANSFER_TIME
|
|
Pass a pointer to a double to receive the time, in seconds, it took from the
|
|
start until the file transfer is just about to begin. This includes all
|
|
pre-transfer commands and negotiations that are specific to the particular
|
|
protocol(s) involved.
|
|
.IP CURLINFO_STARTTRANSFER_TIME
|
|
Pass a pointer to a double to receive the time, in seconds, it took from the
|
|
start until the first byte is just about to be transfered. This includes
|
|
CURLINFO_PRETRANSFER_TIME and also the time the server needs to calculate
|
|
the result.
|
|
.IP CURLINFO_REDIRECT_TIME
|
|
Pass a pointer to a double to receive the total time, in seconds, it took for
|
|
all redirection steps include name lookup, connect, pretransfer and transfer
|
|
before final transaction was started. CURLINFO_REDIRECT_TIME contains the
|
|
complete execution time for multiple redirections. (Added in 7.9.7)
|
|
.IP CURLINFO_REDIRECT_COUNT
|
|
Pass a pointer to a long to receive the total number of redirections that were
|
|
actually followed. (Added in 7.9.7)
|
|
.IP CURLINFO_SIZE_UPLOAD
|
|
Pass a pointer to a double to receive the total amount of bytes that were
|
|
uploaded.
|
|
.IP CURLINFO_SIZE_DOWNLOAD
|
|
Pass a pointer to a double to receive the total amount of bytes that were
|
|
downloaded. The amount is only for the latest transfer and will be reset again
|
|
for each new transfer.
|
|
.IP CURLINFO_SPEED_DOWNLOAD
|

Pass a pointer to a double to receive the average download speed that curl
|
|
measured for the complete download.

|
|
measured for the complete upload.

|
|
received.
|
|
.IP CURLINFO_REQUEST_SIZE

|
|
requests. This is so far only for HTTP requests. Note that this may be more
|
|
than one request if FOLLOWLOCATION is true.
|
|
.IP CURLINFO_SSL_VERIFYRESULT
|
|
Pass a pointer to a long to receive the result of the certification
|
|
verification that was requested (using the CURLOPT_SSL_VERIFYPEER option to
|
|
\fIcurl_easy_setopt(3)\fP).
|
|
.IP CURLINFO_CONTENT_LENGTH_DOWNLOAD

it means that the server didn't send a valid Content-Type header or that the
|
|
protocol used doesn't support this.
|
