💅 glIsShader — straight from the 3G manual, bestie 💅

okay so this is the GLISSHADER(3G) page — the header has a little [FIXME: manual] placeholder moment, no cap — and we're here to talk about glIsShader. It's giving "is this name a shader object or not?" energy, and the answer is literally just GL_TRUE or GL_FALSE. ✨

💖 NAME 💖

glIsShader — determines if a name corresponds to a shader object

🧚 C SPECIFICATION 🧚

GLboolean glIsShader(GLuint shader);

🎀 PARAMETERS 🎀

  • shader — specifies a potential shader object.

✨ DESCRIPTION ✨

glIsShader returns GL_TRUE if shader is the name of a shader object previously created with glCreateShader() and not yet deleted with glDeleteShader(). If shader is zero or a non-zero value that is not the name of a shader object, or if an error occurs, glIsShader returns GL_FALSE. That's the whole vibe check, fr fr. 💅

🦋 NOTES 🦋

  • No error is generated if shader is not a valid shader object name. It's not gonna yell at you, bestie — it just says GL_FALSE and moves on.
  • A shader object marked for deletion with glDeleteShader() but still attached to a program object is still considered a shader object and glIsShader will return GL_TRUE. so like… deleted-ish but not fully gone? iconic behavior, honestly. 👑

🌸 ASSOCIATED GETS 🌸

  • glGetAttachedShaders() with a valid program object
  • glGetShader() with arguments shader and a parameter to be queried
  • glGetShaderInfoLog() with argument object
  • glGetShaderSource() with argument object

and that's the whole page, bestie 🫶 the footer says [FIXME: source], the date is 08/09/2021, and the manual is GLISSHADER(3G). mwah 💋
