curl_free - Man Page

reclaim memory that has been obtained through a libcurl call

Synopsis

#include <curl/curl.h>

void curl_free( char *ptr );

Description

curl_free reclaims memory that has been obtained through a libcurl call.  Use curl_free(3) instead of free() to avoid anomalies that can result from differences in memory management between your application and libcurl.

Passing in a NULL pointer in ptr will make this function return immediately with no action.

Example

  char *width = curl_getenv("COLUMNS");
  if(width) {
    /* it was set! */
    curl_free(width);
  }

Availability

Always

Return Value

None
