range_arrayinbuf(3) Library Functions Manual range_arrayinbuf(3)NAME
range_arrayinbuf - range check for array in buffer
SYNTAX
#include <rangecheck.h>
int range_arrayinbuf(const void* buf,size_t len,
const void* arraystart,
size_t elements,size_t membersize);
DESCRIPTION
range_arrayinbuf checks that the array starting at arraystart consisting of elements members of size membersize each starts and ends within
the buffer buf[0..len-1].
If the array is 0-terminated and you don't know the length beforehand, use range_strinbuf, range_str2inbuf or range_str4inbuf instead.
RETURN VALUE
If the buffer is implausible (buf is NULL or buf+len has an integer overflow), return 0.
If the array is implausible (arraystart is NULL, elements*membersize overflows, or calculating the byte offset of the last element over-
flows), return 0.
If the first or last element of the array points before or after the buffer, return 0.
Otherwise, return 1.

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 *arg, 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 which
will be passed to the curl_formget_callback function.
typedef size_t (*curl_formget_callback)(void *arg, const char *buf, size_t len);
The curl_formget_callback will be executed for each part of the HTTP POST
chain. The void *arg pointer will be the one passed as second argument to
curl_formget(). The character buffer passed to it must not be freed. The
callback should return the buffer length passed to it on success.
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;
}
AVAILABILITY
This function was added in libcurl 7.15.5
