Macros
#define	LOG_LEVEL   LOG_LEVEL_DEBUG
	Default log level if not defined.
#define	_POSIX_C_SOURCE   200809UL
	Expose POSIX extensions for clock_gettime and pthread mutex initializer.
#define	LOG_PRINTF(file, ...)   fprintf(file, __VA_ARGS__)
	Compiler-specific printf abstraction.
#define	LOG_VPRINTF(file, fmt, args)   vfprintf(file, fmt, args)
	Compiler-specific vprintf abstraction.
#define	PREFIX_ERROR   "[ERROR]"
#define	PREFIX_WARNING   "[WARNING]"
#define	PREFIX_INFO   "[INFO]"

#define	COLOR_GREEN   "\033[0;32m"
#define	COLOR_RESET   "\033[0m"
#define	ATTR_PRINTF(fmt_idx, var_idx)    __attribute__((format(printf, fmt_idx, var_idx)))
	Macro to apply GCC printf-style format checking on custom functions.
#define	LOG_ERROR(fmt, ...)
	Logs an error message (red).
#define	LOG_WARNING(fmt, ...)
	Logs a warning message (yellow).
#define	LOG_INFO(fmt, ...)
	Logs an info message (blue).
#define	LOG_DEBUG(fmt, ...)
	Logs a debug message (green).

Enumerations
enum	log_level_t {   LOG_LEVEL_NONE = (uint8_t)(0u) , LOG_LEVEL_ERROR = (uint8_t)(1u) , LOG_LEVEL_WARNING = (uint8_t)(2u) , LOG_LEVEL_INFO = (uint8_t)(3u) ,   LOG_LEVEL_DEBUG = (uint8_t)(4u) }
	Defines log levels for the logging system. More...

Functions
static int	LOG_output (log_level_t level, const char *color, const char *prefix, const char *file, const char *func, int line, const char *fmt,...) __attribute__((format(printf
	Internal logging implementation: thread‐safe, prints timestamp, optional ANSI color, severity prefix, formatted message, and source location.

Detailed Description

Logging macros and configuration for libmemalloc.

Provides logging utilities for libmemalloc, including log level control (ERROR, WARNING, INFO, DEBUG), ANSI color output, and automatic file, function, and line reporting for each log entry. Supports GCC-specific built-in printing as well as standard printf for other compilers.
