Global Mapper SDK
GM_SetLayerUserText
Sets a text string to associate with the layer. This value can be retrieved by calling GM_GetLayerInfo . This text string will persist through a save to a workspace with GM_SaveWorkspace so if you reload that workspace the same text string will be available. This is useful if you want to tie some text to the layer that persists through a save.
