Detailed Description

Macro Definition Documentation

◆ GATEWAY_C_LOGCTL_LINE_MAX

#define GATEWAY_C_LOGCTL_LINE_MAX 16U

Local makros Longest level spelling ("WARNING") + a bit of slack for a trailing newline / stray whitespace on the file's first line.

Definition at line 20 of file gateway_c_logctl.c.

Function Documentation

◆ gateway_c_logctl_poll()

void gateway_c_logctl_poll ( gateway_c_context_t * ctx )

Called once per C cycle (gateway_c_execute()). If SAPI_RBC_LOG_LEVEL_FILE is set and its first line now names a different valid level than last applied, apply it to this process (sapi_log_set_level()) and broadcast a RBC_MSG_SET_LOG_LEVEL frame to A and B (gateway_c_il_handler_broadcast_to_ab()). No-op otherwise - including when the env var is unset, the file is missing, or the content is unchanged/invalid.

Global functions

Parameters

ctx	Gateway context (for the site name in log lines). Must not be NULL.

Definition at line 33 of file gateway_c_logctl.c.

◆ gateway_c_logctl_read_level()

bool gateway_c_logctl_read_level	(	const char *	path,
		sapi_log_level_t *	out_level )

static

Local function declarations

Variable Documentation

◆ s_applied_level

int s_applied_level = -1

static

Local variables declarations Last level actually applied by this module, so an unchanged file is a no-op. Starts at an out-of-range sentinel so the first valid read always "changes".
