NAMEglIsShader − Determines if a name corresponds to a shader object

---

C SPECIFICATIONGLboolean glIsShader(GLuint shader);

---

PARAMETERSshader Specifies a potential shader object​.

---

DESCRIPTIONglIsShader returns GL_TRUE if shader is the name of a shader object previously created with glCreateShader() and not yet deleted with glDeleteShader()​. 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​.

---

NOTESNo 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​.

---

ASSOCIATED GETSglGetAttachedShaders() with a valid program object glGetShader() with arguments shader and a parameter to be queried glGetShaderInfoLog() with argument object glGetShaderSource() with argument object
