NAME¶

glIsShader - Determines if a name corresponds to a shader object

C SPECIFICATION¶

PARAMETERS¶

shader

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
