MPI_T_cvar_get_info - Get the information about a control variable
Input/Output Parameters:
+ name_len - length of the string and/or buffer for name (integer)
- desc_len - length of the string and/or buffer for desc (integer)
Input Parameters:
. cvar_index - index of the control variable to be queried, value between 0 and num_cvar-1 (integer)
Output Parameters:
+ name - buffer to return the string containing the name of the control variable (string)
. verbosity - verbosity level of this variable (integer)
. datatype - MPI datatype of the information stored in the control variable (handle)
. enumtype - optional descriptor for enumeration information (handle)
. desc - buffer to return the string containing a description of the control variable (string)
. binding - type of MPI object this variable is associated with
- scope - scope of when changes to this variable are possible (integer)
