Description
eglGetConfigs returns a list of all
EGL frame buffer configurations that are available for the specified
display.
The items in the list can be used in any EGL function that requires
an EGL frame buffer configuration.
configs does not return values, if it is specified
as
NULL. This is useful for querying just the
number of all frame buffer configurations.
Use eglGetConfigAttrib to retrieve individual attribute values of a frame buffer configuration.
Errors
EGL_FALSE is returned on failure,
EGL_TRUE otherwise.
configs and num_config
are not modified when
EGL_FALSE is returned.
EGL_BAD_DISPLAY is generated if
display is not an EGL display connection.
EGL_NOT_INITIALIZED is generated if
display has not been initialized.
EGL_BAD_PARAMETER is generated if
num_config is NULL.
