"""
Read MSRecord using the ms_readmsr_r function. The following
parameters are directly passed to ms_readmsr_r.
:param ms: _MSStruct (actually consists of a LP_MSRecord,
LP_MSFileParam and an attached file pointer).
Given an existing ms the function is much faster.
:param reclen: If reclen is 0 the length of the first record is auto-
detected. All subsequent records are then expected to have the
same record length. If reclen is negative the length of every
record is automatically detected. Defaults to -1.
:param dataflag: Controls whether data samples are unpacked, defaults
to 1.
:param skipnotdata: If true (not zero) any data chunks read that to do
not have valid data record indicators will be skipped. Defaults to
True (1).
:param verbose: Controls verbosity from 0 to 2. Defaults to None (0).
:param record_number: Number of the record to be read. The first record
has the number 0. Negative numbers will start counting from the end
of the file, e.g. -1 is the last complete record.
