function: rmd160_dup (library) rmd160

Name

rmd160_dup - Duplicate a digest state by making a new instance with the same state.

Synopsis

RMD160 rmd160_dup( RMD160 source )

Description

rmd160_dup duplicates one RMD160 digest instance state making another new instance with a copy of the same state. The caller must release a dynamically allocated instance via rmd160_destroy(). The new instance assumes the state as if it had been appended with exactly the data that has appended the source state. rmd160_dup() is implemented as a macro that calls rmd160_copy().

source is the reference to the RMD160 digest instance which provides the copied state, or is NULL to reference an initial (empty) RMD160 digest instance.

Return values

rmd160_dup returns the reference to the duplicated RMD160 digest instance that received the copied state.

Errors

NULL is returned if a new RMD160 digest instance cannot be allocated.
