Description
The structure mg_error_data is used to return error information.
The code number will be set to one of the MG_ERROR_DATA_CODE_* values defined in civetweb.h.
The meaning of the code_sub number will depend on the value of code.
The code_sub member is experimental and may change in future versions.
The optional pointer text can be used to provide storage for a textual error message.
The size of the provided text pointer must be set in text_buffer_size.
If no textual error message is required and no buffer is probided, text_buffer_size must be set to 0.
Currently struct mg_error_data is used by the functions mg_start2(), mg_start_domain2();, mg_connect_client2(); and mg_get_response2();.
