|

|

| 223 | *
|

| 224 | * Has two principal functionalities: using files and byte arrays as

|
---|
| 226 | * (as the user requests) while for files only the filename and not the

| 227 | * content is stored.
|
---|
| 228 | *
|
---|
| 229 | * While you may have only one byte array for each name, multiple filenames
|
---|
| 230 | * are allowed (and because of this feature CURLFORM_END is needed after
|
---|
| 231 | * using CURLFORM_FILE).
|
---|
| 232 | *
|
---|
| 233 | * Examples:
|
---|
| 234 | *
|
---|
| 235 | * Simple name/value pair with copied contents:
|
---|
| 236 | * curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
|
---|
| 237 | * CURLFORM_COPYCONTENTS, "value", CURLFORM_END);
|
---|
| 238 | *
|
---|
| 239 | * name/value pair where only the content pointer is remembered:
|
---|
| 240 | * curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
|
---|
| 241 | * CURLFORM_PTRCONTENTS, ptr, CURLFORM_CONTENTSLENGTH, 10, CURLFORM_END);
|
---|
| 242 | * (if CURLFORM_CONTENTSLENGTH is missing strlen () is used)
|
---|
| 243 | *
|
---|
| 244 | * storing a filename (CONTENTTYPE is optional!):
|
---|
| 245 | * curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
|
---|
| 246 | * CURLFORM_FILE, "filename1", CURLFORM_CONTENTTYPE, "plain/text",
|
---|
| 247 | * CURLFORM_END);
|
---|
| 248 | *
|
---|
| 249 | * storing multiple filenames:
|
---|
| 250 | * curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
|
---|
| 251 | * CURLFORM_FILE, "filename1", CURLFORM_FILE, "filename2", CURLFORM_END);
|
---|
| 252 | *
|
---|
| 253 | * Returns:
|
---|
| 254 | * CURL_FORMADD_OK on success
|
---|
| 255 | * CURL_FORMADD_MEMORY if the FormInfo allocation fails
|
---|
| 256 | * CURL_FORMADD_OPTION_TWICE if one option is given twice for one Form
|
---|
| 257 | * CURL_FORMADD_NULL if a null pointer was given for a char
|
---|
| 258 | * CURL_FORMADD_MEMORY if the allocation of a FormInfo struct failed
|
---|
| 259 | * CURL_FORMADD_UNKNOWN_OPTION if an unknown option was used
|
---|
| 260 | * CURL_FORMADD_INCOMPLETE if the some FormInfo is not complete (or error)
|
---|
| 261 | * CURL_FORMADD_MEMORY if a HttpPost struct cannot be allocated
|
---|
| 262 | * CURL_FORMADD_MEMORY if some allocation for string copying failed.
|
