Parameters
- pA
- Pointer to the data array storing the finite field element.
- lenA
- Length of the element.
- pR
- Pointer to the context of the finite field element being initialized.
- pGFp
- Pointer to the context of the finite field.
Description
This function initializes the memory buffer
pR
associated with the IppsGFpElement
context and sets up the specific element of the finite field specified by the pGFp
context. The initialized IppsGFpElement
context is used in all the operations with this element of the finite field.If the
lenA
parameter value equals zero, the function initializes a zero element. If the value is less than zero, the function fails.Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or warning.
- ippStsNullPtrErr
- Indicates an error condition in the following cases:
- lenAis not zero and any of the specified pointers isNULL.
- lenAis zero andpRorpGFpisNULL.
- ippStsContextMatchErr
- Indicates an error condition if thepGFpcontext parameter does not match the operation.
- ippStsSizeErr
- Indicates an error condition iflenA≤ 0.
