return a list of all EGL frame buffer configurations for a display
EGLBoolean eglGetConfigs(
| EGLDisplay display, |
EGLConfig * configs, | |
EGLint config_size, | |
EGLint * num_config) |
display
Specifies the EGL display connection.
configs
Returns a list of configs.
config_size
Specifies the size of the list of configs.
num_config
Returns the number of configs returned.
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.
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
.
