  23. .SH NAME
  24. curl_multi_setopt \- set options for a curl multi handle
  25. .SH SYNOPSIS
  26. .nf
  27. #include <curl/curl.h>
  28. CURLMcode curl_multi_setopt(CURLM *multi_handle, CURLMoption option, param);
  29. .fi
  30. .SH DESCRIPTION
  31. \fIcurl_multi_setopt(3)\fP is used to tell a libcurl multi handle how to
  32. behave. By using the appropriate options to \fIcurl_multi_setopt(3)\fP, you
  33. can change libcurl's behavior when using that multi handle. All options are
  34. set with the \fIoption\fP followed by the parameter \fIparam\fP. That
  35. parameter can be a \fBlong\fP, a \fBfunction pointer\fP, an \fBobject
  36. pointer\fP or a \fBcurl_off_t\fP type, depending on what the specific option
  37. expects. Read this manual carefully as bad input values may cause libcurl to
  38. behave badly. You can only set one option in each function call.
