__syslog_chk -- send messages to the system logger, with stack checking


#include <syslog.h>

void __syslog_chk(int priority, int flag, const char * format);


The interface __syslog_chk() shall function in the same way as the interface syslog(), except that __syslog_chk() shall check for stack overflow before computing a result, depending on the value of the flag parameter. If an overflow is anticipated, the function shall abort and the program calling it shall exit.

In general, the higher the value of flag, the more security measures this interface shall take in the form of checking the stack, parameter values, and so on.

The __syslog_chk() function is not in the source standard; it is only in the binary standard.
