NAME
logMessage
- Outputs the log message.
SYNOPSIS
#include <game-carrier/server.h>
typedef void (GC_CORE_API *LogMessage)(
GCT_INT level,
GCT_PTR msg);
typedef struct logMessage {
/* ... Some fields ... */
LogMessage logMessage;
/* ... Some fields ... */
}
Parameters:
level
GCT_INT
Sets the logging level for a message.msg
msg
The message to output.
RETURN VALUE
None.
DESCRIPTION
The logMessage
function outputs the log message.
The level
parameter sets the logging level to determine the severity of logs to be generated.
Supported values: GCL_NORMAL
, GCL_VERBOSE
, GCL_ERR
