mbedtls_mpi_div_mpi() function

Perform a division with remainder of two MPIs: A = Q * B + R

Syntax

int mbedtls_mpi_div_mpi( mbedtls_mpi *Q,     mbedtls_mpi *R,     const mbedtls_mpi *A,     const mbedtls_mpi *B );
Implemented in bignum.c:1547

Arguments

Q

The destination MPI for the quotient. This may be \c NULL if the value of the quotient is not needed.

R

The destination MPI for the remainder value. This may be \c NULL if the value of the remainder is not needed.

A

The dividend. This must point to an initialized MPi.

B

The divisor. This must point to an initialized MPI.

Return value

\c 0 if successful. #MBEDTLS_ERR_MPI_ALLOC_FAILED if memory allocation failed. #MBEDTLS_ERR_MPI_DIVISION_BY_ZERO if \p B equals zero. Another negative error code on different kinds of failure.
