.SH DESCRIPTION
.sp
These two procedures are provided in C to convert from a Fortran status
(which is an array of integers) to a C status (which is a structure),
and vice versa. The conversion occurs on all the information in status,
including that which is hidden. That is, no status information is lost
in the conversion.
.sp
When using \fI\%MPI_Status_f2c\fP, if \fBf_status\fP is a valid Fortran status, but
not the Fortran value of \fBMPI_STATUS_IGNORE\fP or \fBMPI_STATUSES_IGNORE\fP, then
\fI\%MPI_Status_f2c\fP returns in \fBc_status\fP a valid C status with the same
content. If \fBf_status\fP is the Fortran value of \fBMPI_STATUS_IGNORE\fP or
\fBMPI_STATUSES_IGNORE\fP, or if \fBf_status\fP is not a valid Fortran status, then
the call is erroneous.
.sp
When using \fI\%MPI_Status_c2f\fP, the opposite conversion is applied. If
\fBc_status\fP is \fBMPI_STATUS_IGNORE\fP or \fBMPI_STATUSES_IGNORE\fP, or if \fBc_status\fP is
not a valid C status, then the call is erroneous.
.sp
The input status has the same source, tag and error code values as the
output status, and returns the same answers when queried for count,
elements, and cancellation. The conversion function may be called with
an input status argument that has an undefined error field, in which
case the value of the error field in the output status argument is
undefined.
.SH NOTES
.sp
These functions are only available in C; they are not available in any
of the Fortran MPI interfaces.
