Parameters
- pA
- Pointer to the context of the finite field element.
- pStr
- Pointer to the octet string.
- strSize
- Size of the octet string buffer in bytes.
- pGFp
- Pointer to the context of the finite field.
Description
This function extracts the element of the finite field from the context to the octet string. If the string length is not enough to hold the whole finite field element, the function writes only a part of the element.
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or warning.
- ippStsNullPtrErr
- Indicates an error condition if any of the specified pointers isNULL.
- ippStsContextMatchErr
- Indicates an error condition if any of thepGFpandpAcontext parameters does not match the operation.
- ippStsSizeErr
- Indicates an error if the length of the string is zero or negative.
- ippStsOutOfRangeErr
- Indicates an error condition if the elementpAdoes not belong to the finite field specified by the contextpGFp.
