setlogmask

setlogmask()

Set the system log priority mask

Synopsis:

#include <syslog.h>

int setlogmask( int maskpri );

Arguments:

maskpri
The new log priority mask; see below.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The setlogmask() function sets the log priority mask to maskpri and returns the previous mask. Calls to syslog() or vsyslog() with a priority that isn't set in maskpri are rejected.

You can calculate the mask for an individual priority pri with the macro:

LOG_MASK(pri);

You can get the mask for all priorities up to and including toppri with the macro:

LOG_UPTO(toppri);

The default allows all priorities to be logged. See the syslog() function for a list of the priorities.

Returns:

The previous log mask level.

Examples:

See syslog().

Classification:

POSIX 1003.1 XSI
