vsyslog - log message with a stdarg argument list SYNOPSIS
#include <syslog.h> #include <stdarg.h> int vsyslog(int priority, const char *message, va_list ap); DESCRIPTION
The vsyslog() function is identical to syslog(3C), except that it is called with an argument list as defined by <stdarg.h> rather than with a variable number of arguments. EXAMPLES
Example 1: Use vsyslog() to write an error routine. The following demonstrates how vsyslog() can be used to write an error routine. #include <syslog.h> #include <stdarg.h> /* * error should be called like: * error(pri, function_name, format, arg1, arg2...); */ void error(int pri, char *function_name, char *format, ...) { va_list args; va_start(args, format); /* log name of function causing error */ (void) syslog(pri, "ERROR in %s.", function_name); /* log remainder of message */ (void) vsyslog(pri, format, args); va_end(args); (void) abort( ); } main() { error(LOG_ERR, "main", "process %d is dying", getpid()); } ATTRIBUTES
