CT_ReadObject

CK_RV CT_ReadObject(
CK_SESSION_HANDLE hSession,
CK_OBJECT_HANDLE hObj,
unsigned char * buf,
unsigned int len,
unsigned int * pbr);

Get the value of an object.

hSession	open session on the slot containing the object
hObj	object whose value is to be returned
buf	buffer to hold the object value
len	total number of bytes referenced by buf
pbr	reference to int to hold number of bytes copied into buf

buf — contains the object value

*pbr — number of bytes copied into buf

If buf is too small to hold the attribute value (that is, len is < attribute value length), then CKR_ATTRIBUTE_TYPE_INVALID is returned.

To determine the attribute value length, pass in 0 for len, and check the resulting value of *pbr.
