char* gfal_convert_guid_to_lfn	(	plugin_handle	handle,
		char *	guid,
		GError **	err
	)

convert a guid to a lfn link with a call to the lfclib

Parameters:

handle	handle of the lfc plugin
string	of the guid
err	: Error report system

Returns:

: string of the lfn if success or NULL char* if error

int gfal_convert_guid_to_lfn_r	(	plugin_handle	handle,
		const char *	guid,
		char *	buff_lfn,
		size_t	sbuff_lfn,
		GError **	err
	)

convert a guid to a lfn link with a call to the lfclib in a reantrant( buffer mode )

Parameters:

handle	plugin handle
guid	string of the guid
buff_lfn	buffer for the lfn result
sbuff_lfn	size of the buffer
err	: Error report system

Returns:

: 0 else -1 if error and err is set

void gfal_generate_guidG	(	char *	buf,
		GError **	err
	)

generate an uiid string Generate a uuid string and cpy it in the buf,

Warning:

buff must be > uuid size ( 37 bytes )

struct lfc_ops* gfal_load_lfc	(	const char *	name,
		GError **	err
	)		[read]

Resolve the lfc symbols, allow mocking load the shared library and link the symbol for the LFC usage

Parameters:

name	: name of the library
err,:	error report

char* gfal_setup_lfchost	(	gfal_handle	handle,
		GError **	err
	)

setup the lfc_host correctly for the lfc calls

Parameters:

err	GError report system if

Returns:

string of the endpoint, need to be free or NULL if error
