Detailed Description

In certain cases, we may need to get RTAS events from syslog and process them to /var/log/platform (i.e. an EPOW event that allows enough time for the RTAS event(s) to be written to syslog but not enough time for rtas_errd to run).

The search implemeted here checks the last RTAS event number in syslog and /var/log/platform. If they are not equal, we process RTAS events from syslog until they are equal.

Function Documentation

◆ find_event()

char* find_event	(	char *	str,
		int	strlen,
		char *	text,
		int	textlen,
		int	bad_char[]
	)

find_event Search for a RTAS event in the given text. This uses a scaled down version of the Boyer-Moore algorithm. Since we know the search strings we also know there really isn't a good suffix worth looking for. Thus we do not use the good suffix rule for this search.

Parameters

str	string to search for
strlen	length of search string
text	text to search for string in
textlen	length of text to search
bad_char	bad character array for Boyer-Moore search

Returns: pointer to string in text on success, NULL on failure

◆ find_rtas_end()

char* find_rtas_end	(	char *	textstart,
		char *	textend
	)

find_rtas_end

Parameters

textstart	pointer to starting point of search
textend	pointer to ending point of search

Returns: pointer to RTAS event end on success, NULL on failure.

◆ find_rtas_start()

char* find_rtas_start	(	char *	textstart,
		char *	textend
	)

find_rtas_start

Parameters

textstart	pointer to starting point of search
textend	pointer to ending point of search

Returns: pointer to RTAS event start on success, NULL on failure.

◆ get_rtas_no()

int get_rtas_no ( char * ptr )

get_rtas_no Retrieve the RTAS event number from an RTAS event. NOTE: this routine assumes the pointer passed in is the result from a call to find_rtas_start()

Parameters
