MPI_Info_set - Adds a key/value pair to info.
#include <mpi.h>
int MPI_Info_set(MPI_Info info, char *key, char *value)

MPI_INFO_SET(INFO, KEY, VALUE, IERROR)
INTEGER INFO, IERROR

#include <mpi.h>
void MPI::Info::Set(const char* key, const char* value)
- info
- Info object (handle).
- key
- Key
(string).
- value
- Value (string).
- IERROR
- Fortran only: Error
status (integer).
MPI_Info_set adds the (key,value) pair to
info and overrides the value if a value for the same key was previously
set. The key and value parameters are null-terminated strings in C. In Fortran,
leading and trailing spaces in key and value are stripped. If either key
or value is larger than the allowed maximums, the error MPI_ERR_INFO_KEY
or MPI_ERR_INFO_VALUE is raised, respectively.
Almost all MPI routines
return an error value; C routines as the value of the function and Fortran
routines in the last argument. C++ functions do not return errors. If the
default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error
the C++ exception mechanism will be used to throw an MPI::Exception object.
Before the error value is returned, the current MPI error handler is called.
By default, this error handler aborts the MPI job, except for I/O function
errors. The error handler may be changed with MPI_Comm_set_errhandler; the
predefined error handler MPI_ERRORS_RETURN may be used to cause error values
to be returned. Note that MPI does not guarantee that an MPI program can
continue past an error.
