SYNOPSIS #include <Tt/tt_c.h> void tt_error ( const char *funcname, Tt_status status ); DESCRIPTION The tt_error() function is a publicly-known null function. This func- tions is called by the ToolTalk library just before it returns from any ToolTalk API call that has a status other than TT_OK. The name of the function that is about to return and the status code is passed. You can use this call to set a dbx breakpoint in tt_error to quickly catch and trace back any ToolTalk errors. You can also interpose this function, for example, to log ToolTalk errors to stderr. APPLICATION USAGE 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)); } ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+------------------+ |Availability | library/tooltalk | +---------------+------------------+ |Stability | Committed | +---------------+------------------+ SEE ALSO tt_c(5) ToolTalk 1.3 1 March 1996 tt_error(3)
