Replace use of fixed macro BUFSIZE to define the size of the receive buffer. Reappropriate CURLOPT_BUFFERSIZE to include enlarging receive buffer size. Upon setting, resize buffer if larger than the current default size up to a MAX_BUFSIZE (512KB). This can benefit protocols like SFTP. Closes #1222

|
|
.SH NAME
|
|
curl_easy_setopt \- set options for a curl easy handle
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLoption option, parameter);
|
|
.SH DESCRIPTION
|
|
\fIcurl_easy_setopt(3)\fP is used to tell libcurl how to behave. By setting
|
|
the appropriate options, the application can change libcurl's behavior. All
|
|
options are set with an \fIoption\fP followed by a \fIparameter\fP. That
|
|
parameter can be a \fBlong\fP, a \fBfunction pointer\fP, an \fBobject
|
|
pointer\fP or a \fBcurl_off_t\fP, depending on what the specific option
|
|
expects. Read this manual carefully as bad input values may cause libcurl to
|
|
behave badly! You can only set one option in each function call. A typical
|
|
application uses many \fIcurl_easy_setopt(3)\fP calls in the setup phase.
|
|
|
|
Options set with this function call are valid for all forthcoming transfers
|
|
performed using this \fIhandle\fP. The options are not in any way reset
|
|
between transfers, so if you want subsequent transfers with different options,
|
|
you must change them between the transfers. You can optionally reset all
|
|
options back to internal default with \fIcurl_easy_reset(3)\fP.
|
|
|
|
Strings passed to libcurl as 'char *' arguments, are copied by the library;
|
|
thus the string storage associated to the pointer argument may be overwritten
|
|
after \fIcurl_easy_setopt(3)\fP returns. The only exception to this rule is
|
|
really \fICURLOPT_POSTFIELDS(3)\fP, but the alternative that copies the string
|
|
\fICURLOPT_COPYPOSTFIELDS(3)\fP has some usage characteristics you need to
|
|
read up on.
|
|
|
|
The order in which the options are set does not matter.
|
|
|
|
Before version 7.17.0, strings were not copied. Instead the user was forced
|
|
keep them available until libcurl no longer needed them.
|
|
|
|
The \fIhandle\fP is the return code from a \fIcurl_easy_init(3)\fP or
|
|
\fIcurl_easy_duphandle(3)\fP call.
