Typedef Documentation

typedef struct gfal_handle_* gfal2_context_t

a gfal context is a separated instance of the gfal library Each context owns his parameters, file descriptors Context allows to have separated instance of GFAL with differents parameters providing an advanced interface to GFAL

Function Documentation

void gfal2_context_free

(

gfal2_context_t

context

)

free a gfal2 context It is safe to delete a NULL context Thread-safe

gfal2_context_t gfal2_context_new

(

GError **

err

)

create a gfal2 context

Each context contain its own set of parameters and configurations ( Parameter API )

A context can be used in multiple threads at the same time ( Thread-safe ).

Parameters

err	: GError error report system

Returns

a context if success, NULL if error

GFAL2_DEPRECATED

(

gfal2_context_new

)

Deprecated:

same than gfal2_context_new but with old compatibility

GFAL2_DEPRECATED

(

gfal2_context_free

)

Deprecated:

GQuark gfal2_get_config_quark

(

)

GQuark for the gfal2 config namespace GQuark are used by the GError gfal2 error system in order to determine the scope of one error GQuark String : "GFAL2::CONFIG"

GQuark gfal2_get_core_quark

(

)

GQuark for the gfal2 core namespace GQuark are used by the GError gfal2 error system in order to determine the scope of one error GQuark String : "GFAL2::CORE"

GQuark gfal2_get_plugins_quark

(

)

GQuark for the gfal2 plugin namespace GQuark String : "GFAL2::PLUGINS" Any Plugin specific GQuark follows this pattern GFAL2::PLUGINS::NAME example srm plugin : GFAL2::PLUGINS::SRM
