Creating two separable programs, one with a vertex shader and one with a fragment shader.
//Create two separable program objects from a
//single source string respectively (vertSrc and fragSrc)
GLuint vertProg = glCreateShaderProgramv(GL_VERTEX_SHADER , 1, &vertSrc);
GLuint fragProg = glCreateShaderProgramv(GL_FRAGMENT_SHADER, 1, &fragSrc);
//CHECK FOR ERRORS HERE!.
//Generate a program pipeline and bind the programs to their respective stages
glGenProgramPipelines(1, &pipeline);
glUseProgramStages(pipeline, GL_VERTEX_SHADER_BIT , vertProg);
glUseProgramStages(pipeline, GL_FRAGMENT_SHADER_BIT, fragProg);
//Query and set any uniforms
GLint colorLoc = glGetUniformLocation(fragProg, "Color");
glProgramUniform4f(fragProg, colorLoc, 1.f, 0.f, 0.f, 1.f);
