SHA2UPDATE224, SHA2UPDATE256, SHA2UPDATE384, and SHA2UPDATE512

Use a token initialized by the corresponding SHA2INIT function to perform an intermediate hash of an element in a series of texts.

t

A token returned by a previous invocation of SHA2INITx or SHA2UPDATEx.

p

A pointer that specifies the address of a buffer to be added to the hash.

n

An expression that specifies the length (in bytes) of that buffer. It must have a computational type and will be converted to type size_t.

These functions return a token (of type POINTER) that can be used with further SHA2UPDATE functions and the concluding SHA2FINAL function.

See the description of the SHA2FINAL functions for an example.
