mbedtls_ecp_copy() function

This function copies the contents of point \p Q into point \p P.

Syntax

int mbedtls_ecp_copy( mbedtls_ecp_point *P,     const mbedtls_ecp_point *Q );
Implemented in ecp.c:642

Arguments

P

The destination point. This must be initialized.

Q

The source point. This must be initialized.

Return value

\c 0 on success. #MBEDTLS_ERR_MPI_ALLOC_FAILED on memory-allocation failure. Another negative error code for other kinds of failure.
