#define	DEBUG_INFO(fmt, ...)
	Print debug message with file and line info.

Functions
void	clibs_set_output (FILE *out, FILE *err)
	Sets thread-local output and error streams.
FILE *	clibs_get_out (void)
	Gets current output stream (fallback: stdout).
FILE *	clibs_get_err (void)
	Gets current error stream (fallback: stderr).

Detailed Description

Thread-aware printing macros with redirect support.

This module provides print macros (like printf, puts) that redirect output to thread-local FILE* streams, with fallback to stdout/stderr. Intended for portable, lock-free console or file printing.

clibs_get_err()

FILE * clibs_get_err

(

void

)

Gets current error stream (fallback: stderr).

Gets current error stream (fallback: stderr).

Falls back to stderr if no thread-local error stream is set.

Returns

FILE* current error stream.

clibs_get_out()

FILE * clibs_get_out

(

void

)

Gets current output stream (fallback: stdout).

Gets current output stream (fallback: stdout).

Falls back to stdout if no thread-local output stream is set.

Returns

FILE* current output stream.

clibs_set_output()

void clibs_set_output	(	FILE *	out,
		FILE *	err )

Sets thread-local output and error streams.

Parameters

out	Stream for normal output (default: stdout).
err	Stream for error output (default: stderr).

Sets thread-local output and error streams.

Parameters

out	Output stream for general messages (default fallback: stdout).
err	Output stream for log messages (default fallback: stderr).
