2018 The Khronos Group Inc. eglGetSyncAttrib 3G eglGetSyncAttrib Return an attribute of a sync object EGLBoolean eglGetSyncAttrib (EGLDisplay display EGLSync sync EGLint attribute EGLAttrib *value display Specifies the EGL display connection. sync Specifies the sync object to query. attribute Specifies the EGL sync object attribute to query. value Returns the requested attribute value. eglGetSyncAttrib is used to query attributes of the sync object sync. Legal values for attribute depend on the type of sync object, as shown in table . Assuming no errors are generated, EGL_TRUE is returned and the value of the queried attribute is returned in *value. Attribute Description Supported Sync Objects Attribute Description Supported Sync Objects EGL_SYNC_TYPE Type of the sync object All EGL_SYNC_STATUS Status of the sync object All EGL_SYNC_CONDITION Signaling condition EGL_SYNC_FENCE or EGL_SYNC_CL_EVENT On failure, eglGetSyncAttrib returns EGL_FALSE and *value is not modified. If sync is not a valid sync object for display, an EGL_BAD_PARAMETER error is generated. If attribute is not one of the attributes in table , an EGL_BAD_ATTRIBUTE error is generated. If attribute is not supported for the type of sync object passed in sync, an EGL_BAD_MATCH error is generated. If display does not match the display passed to eglCreateSync when sync was created, behaviour is undefined. eglGetSyncAttrib is available only if the EGL version is 1.5 or greater. eglCreateSync
