✨ NAME ✨

okay so this is the GLGETFRAGDATALOCATIO(3G) page, bestie — and glGetFragDataLocation is literally here to query the bindings of color numbers to user-defined varying out variables 💅

🌸 C SPECIFICATION 🌸

GLint glGetFragDataLocation(GLuint program, const char * name);

🎀 PARAMETERS 🎀

  • program — the name of the program containing the varying out variable whose binding you wanna query 🫶
  • name — the name of the user-defined varying out variable whose binding you wanna query ✨

💖 DESCRIPTION 💖

glGetFragDataLocation retrieves the assigned color number binding for the user-defined varying out variable name for program program.

program must have previously been linked — no cap, that part matters.

name must be a null-terminated string.

If name is not the name of an active user-defined varying out fragment shader variable within program, -1 will be returned. yep, that’s the vibe check result 😭

🦋 ERRORS 🦋

  • GL_INVALID_OPERATION is generated if program is not the name of a program object.
like, don’t hand it something that isn’t a program object and expect main character energy, okay? 💀
