NAME

curl_free - reclaim memory that has been obtained through a libcurl call

SYNOPSIS

#include <curl/curl.h>

void curl_free(void *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 makes this function return immediately with no action.

EXAMPLE

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

AVAILABILITY

RETURN VALUE

None
