Query the value of an integer-valued batch attribute.
A non-zero return value indicates that a problem occurred while querying the attribute. Refer to the Error Code table for a list of possible return values. Details on the error can be obtained by calling GRBgeterrormsg.
batch: A batch structure, typically created by routine GRBgetbatch.
attrname: The name of an integer-valued batch attribute. Available attributes are listed and described in the Attributes section of this document.
valueP: The location in which the current value of the requested attribute should be placed.
/* query the last error code */ error = GRBgetbatchintattr(batch, "BatchErrorCode", &errorCode); if (error || !errorCode) goto QUIT;
Note that all Batch attributes are cached locally, and are only updated when you create a client-side batch object or when you explicitly update this cache (by calling the appropriate update function - GRBupdatebatch for C, update for Python, etc.).
