NAME

       glIsShader - Determines if a name corresponds to a shader object

C SPECIFICATION

       GLboolean glIsShader(GLuint shader);

PARAMETERS

       shader
           Specifies a potential shader object.

DESCRIPTION

       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.

NOTES

       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.

ASSOCIATED GETS

       glGetAttachedShaders() with a valid program object

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

       glGetShaderInfoLog() with argument object

       glGetShaderSource() with argument object
