GLGETSHADERINFOLOG(3G)

✨ NAME ✨

glGetShaderInfoLog — returns the information log for a shader object. Yes bestie, this is the GLGETSHADERINFOLOG(3G) page, and we’re getting into it 💅

🧾 C SPECIFICATION 🧾

void glGetShaderInfoLog(GLuint shader, GLsizei maxLength,
                        GLsizei *length, GLchar *infoLog);

🎀 PARAMETERS 🎀

• shader — the shader object whose information log you’re querying, periodt.
• maxLength — the size of the character buffer that’s gonna store the returned information log.
• length — returns the length of the string returned in infoLog, and that’s excluding the null terminator.
• infoLog — an array of characters used to return the information log.

---

🦋 DESCRIPTION 🦋

glGetShaderInfoLog returns the information log for the specified shader object. The info log for a shader object gets modified when the shader is compiled, and the string that comes back will be null terminated, no cap.

glGetShaderInfoLog returns as much of the information log as it can into infoLog, up to a maximum of maxLength characters. The number of characters actually returned — excluding the null termination character — is specified by length. If you don’t need the length of the returned string, you can pass NULL in the length argument. The size of the buffer required to store the returned information log can be obtained by calling glGetShader() with the value GL_INFO_LOG_LENGTH.

The information log for a shader object is a string that may contain diagnostic messages, warning messages, and other information about the last compile operation. When a shader object is created, its information log will be a string of length 0. iconic behavior honestly.

👑 NOTES 👑

The information log for a shader object is the OpenGL implementer’s primary mechanism for conveying information about the compilation process. So yeah, it can be helpful to application developers during the development process, even when compilation is successful. Application developers should not expect different OpenGL implementations to produce identical information logs. fr fr, don’t assume they’ll match.

💀 ERRORS 💀

• GL_INVALID_VALUE is generated if shader is not a value generated by OpenGL.
• GL_INVALID_OPERATION is generated if shader is not a shader object.
• GL_INVALID_VALUE is generated if maxLength is less than 0.

---

🌈 ASSOCIATED GETS 🌈

• glGetShader() with argument GL_INFO_LOG_LENGTH
• glIsShader()
