GLISSHADER(3G)                                   OpenGL 3.3                                   GLISSHADER(3G)



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
