Detailed Description

Macro-based logging implementation.

Macro Definition Documentation

◆ _POSIX_C_SOURCE

#define _POSIX_C_SOURCE 200809L

Definition at line 6 of file log.c.

Function Documentation

◆ cwist_log_write()

void cwist_log_write	(	cwist_macro_log_level_t	level,
		const char *	fmt,
			...
	)

Write a single log record to stderr with a timestamp and level tag.

Write a log message to stderr.

Emits one line of the form [LEVEL] [YYYY-MM-DD HH:MM:SS] <formatted message> to stderr. Unknown level values print as ???. Output is not buffered beyond the C runtime's default stderr buffering; no synchronization is performed, so interleaving may occur when called concurrently from multiple threads.

Parameters

level	Severity tag for the record (INFO, WARN, ERROR, DEBUG, or other).
fmt	printf-style format string, followed by its arguments.

◆ g_cwist_log_level

cwist_macro_log_level_t g_cwist_log_level = CWIST_LOG_LEVEL_NONE
