✨ NAME ✨

okay so this is the GLUSEPROGRAMSTAGES(3G) manual page, bestie 💖. The function is glUseProgramStages, and it binds stages of a program object to a program pipeline. That’s the whole vibe. periodt.

💻 C SPECIFICATION

void glUseProgramStages(GLuint pipeline, GLbitfield stages,
                        GLuint program);

🎀 PARAMETERS

  • pipeline — the program pipeline object you’re binding stages from program into. main character object energy.
  • stages — the set of program stages to bind to the program pipeline object. This is a bitmask situation, iykyk.
  • program — the program object containing the shader executables to use in pipeline. slay.

🫶 DESCRIPTION

okay so here’s the tea: glUseProgramStages binds executables from a program object associated with a specified set of shader stages to the program pipeline object given by pipeline. pipeline specifies the program pipeline object to which to bind the executables. stages contains a logical combination of bits indicating the shader stages to use within program with the program pipeline object pipeline.

stages must be a logical combination of GL_VERTEX_SHADER_BIT, GL_TESS_CONTROL_SHADER_BIT, GL_TESS_EVALUATION_SHADER_BIT, GL_GEOMETRY_SHADER_BIT, GL_FRAGMENT_SHADER_BIT and GL_COMPUTE_SHADER_BIT. Additionally, the special value GL_ALL_SHADER_BITS may be specified to indicate that all executables contained in program should be installed in pipeline. iconic bitmask behavior ✨.

If program refers to a program object with a valid shader attached for an indicated shader stage, glUseProgramStages installs the executable code for that stage in the indicated program pipeline object pipeline. If program is zero, or refers to a program object with no valid shader executable for a given stage, it is as if the pipeline object has no programmable stage configured for the indicated shader stages. If stages contains bits other than those listed above, and is not equal to GL_ALL_SHADER_BITS, an error is generated.

📝 NOTES

The GL_COMPUTE_SHADER_BIT bit is available only if the GL version is 4.3 or greater. write that down 📝.

💀 ERRORS

  • GL_INVALID_VALUE is generated if shaders contains set bits that are not recognized, and is not the reserved value GL_ALL_SHADER_BITS. (yes, the original says shaders here — we’re not fixing it, bestie 💅)
  • GL_INVALID_OPERATION is generated if program refers to a program object that was not linked with its GL_PROGRAM_SEPARABLE status set.
  • GL_INVALID_OPERATION is generated if program refers to a program object that has not been successfully linked.
  • 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().
vibe check warning: these errors are not a drill. check your pipeline names and your GL_PROGRAM_SEPARABLE status, fr fr.
