glIsShader - Determines if a name corresponds to a shader object
GLboolean glIsShader(GLuint shader);
shader
glIsShader 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.
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.

glGetShader() with arguments shader and a parameter to be queried
glGetShaderInfoLog() with argument object
