  25. .TH CURLOPT_MAX_SEND_SPEED_LARGE 3 "January 02, 2023" "libcurl 7.88.1" "curl_easy_setopt options"
  26. .SH NAME
  27. CURLOPT_MAX_SEND_SPEED_LARGE \- rate limit data upload speed
  28. .SH SYNOPSIS
  29. .nf
  30. #include <curl/curl.h>
  31. CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAX_SEND_SPEED_LARGE,
  32. curl_off_t maxspeed);
  33. .SH DESCRIPTION
  34. Pass a curl_off_t as parameter with the \fImaxspeed\fP. If an upload exceeds
  35. this speed (counted in bytes per second) the transfer will pause to keep the
  36. speed less than or equal to the parameter value. Defaults to unlimited
  37. speed.
  38. This is not an exact science. libcurl attempts to keep the average speed below
  39. the given threshold over a period time.
  40. If you set \fImaxspeed\fP to a value lower than
  41. \fICURLOPT_UPLOAD_BUFFERSIZE(3)\fP, libcurl might "shoot over" the limit on
  42. its first send and still send off a full buffer.
  43. This option does not affect transfer speeds done with FILE:// URLs.
  44. .SH DEFAULT
  45. 0, disabled
  46. .SH PROTOCOLS
  47. All except file://
  48. .SH EXAMPLE
  49. .nf
  50. CURL *curl = curl_easy_init();
  51. if(curl) {
  52. CURLcode ret;
  53. curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
  54. /* cap the upload speed to 1000 bytes/sec */
  55. curl_easy_setopt(curl, CURLOPT_MAX_SEND_SPEED_LARGE, (curl_off_t)1000);
  56. /* (set some upload options as well!) */
  57. ret = curl_easy_perform(curl);
  58. }
