C Specification[edit]

void glActiveShaderProgram( GLuint pipeline, GLuint program );


Parameters[edit]

pipeline - Specifies the program pipeline object to set the active program object for.

Description[edit]

 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[edit]

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