GLISTEXTURE(3G)

📦 version 24.3.3, in opensuse-leap 16.0

okay bestie, welcome to the GLISTEXTURE(3G) page from the 3G manual — we're doing a texture-name vibe check, and yes, it's exactly as iconic as it sounds. 💅

💖 NAME 💖

glIsTexture — determine if a name corresponds to a texture. That's it, that's the whole assignment. ✨

✨ C SPECIFICATION ✨

GLboolean glIsTexture( GLuint texture )

🎀 PARAMETERS 🎀

  • texture — a value that may be the name of a texture. That's the whole input, bestie. 🫶

🌸 DESCRIPTION 🌸

glIsTexture returns GL_TRUE if texture is currently the name of a texture. If texture is zero, or if it's a non-zero value that is not currently the name of a texture, or if an error occurs, glIsTexture returns GL_FALSE. No cap, that's the whole decision tree. 😭

🦋 NOTES 🦋

glIsTexture is available only if the GL version is 1.1 or greater. So if your GL is older than that, this function is not invited to the party. 💀

🔥 ERRORS 🔥

GL_INVALID_OPERATION is generated if glIsTexture is executed between the execution of glBegin and the corresponding execution of glEnd.

bestie, do not call this inside a glBegin/glEnd sandwich — that's the exact situation that generates GL_INVALID_OPERATION. 🚨
