Catch errors
Errors used in GMM++ are defined in the file gmm/gmm_except.h. In order to make easier the error
catching all errors derive from the type std::logic_error defined in the file
stdexcept of the S.T.L.
A standard procedure, GMM_STANDARD_CATCH_ERROR, is defined in
gmm/gmm_except.h. This procedure
catches all errors and print the error message when an error
occurs. It can be used in the main procedure of the program as
follows
int main(void) {
try {
... main program ...
}
GMM_STANDARD_CATCH_ERROR;
}
It is highly recommended to catch the errors at least in the main function, because if you do not so, you will not be able to see error messages.
