NAME

       rangecheck.h - pointer range checking

SYNTAX

       #include <rangecheck.h>

       int range_validbuf(const void* buf,size_t len);

       int range_ptrinbuf(const void* buf,size_t len,const void* ptr);

       int range_bufinbuf(const void* buf1,size_t len1,
			  const void* buf2,size_t len2);

       int range_arrayinbuf(const void* buf,size_t len,
			    const void* arraystart,
			    size_t elements,size_t membersize);

       int range_strinbuf(const void* buf,size_t len,const void* string);

       int range_str2inbuf(const void* buf,size_t len,const void* string);

       int range_str4inbuf(const void* buf,size_t len,const void* string);

DESCRIPTION

       rangecheck.h  provides several routines for range checking pointers.  These routines are meant for code that has to validate the syntax and
       semantics of buffers coming in from untrusted sources (like a network connection or an input file).

RETURN VALUE

       The routines all return 0 on error, or 1 if the pointers were in range.

curl_formget(3) 						  libcurl Manual						   curl_formget(3)

NAME

       curl_formget - serialize a previously built multipart/formdata HTTP POST chain

SYNOPSIS

       #include <curl/curl.h>

       void curl_formget(struct curl_httppost * form, void *userp,
			 curl_formget_callback append );

DESCRIPTION

       curl_formget()  is  used  to serialize data previously built/appended with curl_formadd(3). Accepts a void pointer as second argument named
       userp which will be passed as the first argument to the curl_formget_callback function.

       typedef size_t (*curl_formget_callback)(void *userp, const char *buf,  size_t len);

       The curl_formget_callback will be executed for each part of the HTTP POST chain. The character buffer passed to the callback  must  not	be
       freed. The callback should return the buffer length passed to it on success.

       If  the CURLFORM_STREAM option is used in the formpost, it will prevent curl_formget(3) from working until you've performed the actual HTTP
       request as only then will libcurl get the actual read callback to use!

RETURN VALUE

       0 means everything was ok, non-zero means an error occurred

EXAMPLE

	size_t print_httppost_callback(void *arg, const char *buf, size_t len)
	{
	  fwrite(buf, len, 1, stdout);
	  (*(size_t *) arg) += len;
	  return len;
	}

	size_t print_httppost(struct curl_httppost *post)
	{
	  size_t total_size = 0;
	  if(curl_formget(post, &total_size, print_httppost_callback)) {
	    return (size_t) -1;
	  }
	  return total_size;
	}
