MPI_T_enum_get_info - Query information about an enumerator
#include <mpi.h> int MPI_T_enum_get_info(MPI_T_enum enumtype, int *num, char *name, int *name_len)
- Enumerator to be queried.
- Length of the string and/or buffer for name.
MPI_T_enum_get_info can be used to query information about an enumerator. The function returns the number of discrete values represented by this enumerator in the num parameter.
This MPI tool interface function returns the name of the enumeration as a string. This function takes two argument for the string: name which specifies a buffer where the name of the should be stored, and name_len which must initially specify the size of the buffer pointed to by name. This function will copy at most name_len - 1 characters of the name and sets name_len to the number of characters returned + 1. If name_len is NULL or the value specified in name_len is 0 the name buffer is ignored and the name of the enumeration is not returned.
MPI_T_enum_get_info() will fail if:
- The MPI Tools interface not initialized
- The enumeration is invalid or has been deleted
