glIsShader
Core in version 4.5
Core since version 2.0

glIsShader: Determines if a name corresponds to a shader object

Function Definition

 GLboolean glIsShader(GLuint shader);
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
