# Gl.GetAttachedShaders (gb.opengl.glsl)

Static Function GetAttachedShaders ( Program As Integer ) As Integer[]

Returns the handles of the shader objects attached to a program object.

### Parameters

program

  Specifies the program object to be queried.

maxCount

  Specifies the size of the array for storing the returned object names.

count

  Returns the number of names actually returned in objects.

shaders

  Specifies an array that is used to return the names of attached shader objects.

### Description

Gl.GetAttachedShaders returns the names of the shader objects attached to program. The names of shader objects that are attached to program will be returned in shaders. The actual number of shader names written into shaders is returned in count. If no shader objects are attached to program, count is set to 0. The maximum number of shader names that may be returned in shaders is specified by maxCount.

If the number of names actually returned is not required (for instance, if it has just been obtained by calling Gl.GetProgram), a value of NULL may be passed for count. If no shader objects are attached to program, a value of 0 will be returned in count. The actual number of attached shaders can be obtained by calling Gl.GetProgram with the value Gl.ATTACHED_SHADERS.

### Errors

Gl.INVALID_VALUE is generated if program is not a value generated by OpenGL.

Gl.INVALID_OPERATION is generated if program is not a program object.

Gl.INVALID_VALUE is generated if maxCount is less than 0.

### Associated Gets
