]]> ]]> tt_error library call tt_error capture ToolTalk function errors #include <Tt/tt_c.h> void tt_error const char *funcname Tt_status status The tt_error function is a publicly-known null function. It is called by the ToolTalk library just before it returns from any ToolTalk API call that has a status other than TT_OK. The caller passes the name of the function that is about to return and the function's status code. You can use this function to set a dbx breakpoint to quickly catch and trace back any ToolTalk errors. You can also interpose this function, for example, to log ToolTalk errors to stderr. funcname Specifies the name of the function. status Specifies the function's return status value. None. The following code example shows how an application might interpose this function to log ToolTalk errors to stderr: void tt_error(const char *funcname, Tt_status status) { fprintf(stderr, "ToolTalk function %s returned %s.\n", funcname, tt_status_message(status)); } &cdeman.Tt.tt.c.h;
