If shader is zero or a non-zero value that is not the name of a shader object, or if an error occurs, glIsShader returns GL_FALSE. No error is generated if shader is not a valid shader object name. A shader object marked for deletion with glDeleteShader but still attached to a program object is still considered a shader object and glIsShader will return GL_TRUE. glGetAttachedShaders with a valid program object glGetShader with arguments shader and a parameter to be queried glGetShaderInfoLog with argument object glGetShaderSource with argument object glAttachShader, glCompileShader, glCreateShader, glDeleteShader, glDetachShader, glLinkProgram, glShaderSource Copyright 2003-2005 3Dlabs Inc.
