glIsShader — Determines if a name corresponds to a shader object
GLboolean glIsShader(
|
GLuint shader); |
shader
Specifies a potential shader object.
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.
glGetAttachedShaders with a valid program object
glGetShader
with arguments shader and a parameter to
be queried
glGetShaderInfoLog
