mbedtls_mpi_lsb() function

Return the number of bits of value \c 0 before the least significant bit of value \c 1.

Syntax

size_t mbedtls_mpi_lsb( const mbedtls_mpi *X );
Implemented in bignum.c:380

Arguments

X

The MPI to query.

Return value

The number of bits of value \c 0 before the least significant bit of value \c 1 in \p X.

Notes

This is the same as the zero-based index of the least significant bit of value \c 1.
