Function Documentation

char* base64	(	const unsigned char *	str,
		int	n
	)

convert the input to base64

Parameters:

input	the input string
size	of the input string

Returns:

a newly allocated string with the base64 data which should be free'd by the user

Definition at line 38 of file util.c.

char* concat	(	char *	a,
		char *	b
	)

Returns:

null if a or b is null, a + "/" + b otherwise

Definition at line 279 of file util.c.

static char* get_command_line

(

int

pid

)

[static]

get the command line corresponding to a process

Parameters:

pid	process id

Returns:

a base64 encoded string with the process command line, or an empty string if it could not be extrcated

Definition at line 80 of file util.c.

int get_limit	(	int	argc,
		char **	argv
	)

look for the limit "--" in argv argument number arguments

Returns:

the index of the limit, argc if it is not found

Definition at line 218 of file util.c.

void set_timestamp

(

char *

timestamp

)

get a string representing the time in ISO8601 format

Parameters:

timestamp

string to set to the given time

Returns:

void
