glActiveShaderProgram: set the active program object for a program pipeline object

Function Definition

 void glActiveShaderProgram(GLuint pipeline​, GLuint program​);
pipeline
Specifies the program pipeline object to set the active program object for.
program
Specifies the program object to set as the active program pipeline object pipeline​.

Description

glActiveShaderProgram sets the linked program named by program​ to be the active program for the program pipeline object pipeline​. The active program in the active program pipeline object is the target of calls to glUniform when no program has been made current through a call to glUseProgram.

Errors

GL_INVALID_OPERATION is generated if pipeline​ is not a name previously returned from a call to glGenProgramPipelines or if such a name has been deleted by a call to glDeleteProgramPipelines.

GL_INVALID_VALUE is generated if program​ is not a valid program object or shader object name.

GL_INVALID_OPERATION is generated if program​ is a shader object.

GL_INVALID_OPERATION is generated if program​ refers to a program object that has not been successfully linked.
