NAMEMPI_Info_set − Adds a key/value pair to info.

---

SYNTAX

---

C Syntax#include <mpi.h> int MPI_Info_set(MPI_Info info, char *key, char *value)

---

Fortran SyntaxINCLUDE 'mpif.h' MPI_INFO_SET(INFO, KEY, VALUE, IERROR) INTEGER INFO, IERROR CHARACTER*(*) KEY, VALUE

---

C++ Syntax#include <mpi.h> void MPI::Info::Set(const char* key, const char* value)

---

INPUT/OUTPUT PARAMETERinfo  Info object (handle).

---

INPUT PARAMETERSkey  Key (string). value  Value (string).

---

OUTPUT PARAMETERIERROR  Fortran only: Error status (integer).

---

DESCRIPTIONMPI_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.

---

ERRORSAlmost 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.
