Summary

Declaration

Definition

from bignum_core.h:298

int mbedtls_mpi_core_write_be(const mbedtls_mpi_uint *A, size_t A_limbs, unsigned char *output, size_t output_length);

Implemented in bignum_core.c:291

Arguments

Argument

Description

The address of the MPI.

A_limbs

The number of limbs of \p A.

output

The output buffer to export to.

output_length

The length in bytes of \p output.

Return value

\c 0 if successful. #MBEDTLS_ERR_MPI_BUFFER_TOO_SMALL if \p output isn't large enough to hold the value of \p A.

Notes

If \p output is shorter than \p A the export is still successful if the value held in \p A fits in the buffer (that is, if enough of the most significant bytes of \p A are 0).
