void _stp_print (  const char *  fmt,   ... )

Prints to the trace buffer. This function uses the same formatting as printk. It currently writes to the system log. Parameters: fmt  A variable number of args. Todo: Needs replaced with something much faster that does not use the system log. Definition at line 43 of file io.c. Referenced by _stp_symbol_print().

void _stp_print_str (  char *  str  )

Prints to the trace buffer. This function will write a string to the trace buffer. It currently writes to the system log. Parameters: str  String. Todo: Needs replaced with something much faster that does not use the system log. Definition at line 60 of file io.c.

void dlog (  const char *  fmt,   ... )

Logs Data. This function is compatible with printk. In fact it currently sends all output to vprintk, after sending "STP: ". This allows us to easily detect SystemTap output in the log file. Parameters: fmt  A variable number of args. Bug: Lines are limited in length by printk buffer. If there is no newline in the format string, then other syslog output could get appended to the SystemTap line. Todo: Either deprecate or redefine this as a way to log debug or status messages, separate from the normal program output. Definition at line 25 of file io.c. Referenced by _stp_list_clear(), _stp_register_jprobes(), _stp_register_kprobes(), _stp_unregister_jprobes(), and _stp_unregister_kprobes().
