GLGETPROGRAMINFOLOG(3G)

Hey bestie 💖 welcome to the GLGETPROGRAMINFOLOG(3G) page — manual name: [FIXME: manual], iconic. We're talking about glGetProgramInfoLog, and it's literally the function that hands you the info log for a program object. Buckle up 🎀

✨ NAME ✨

glGetProgramInfoLog — returns the information log for a program object. That's the whole vibe: you ask a program object for its info log, and it gives you the tea ☕.

🎀 C SPECIFICATION 🎀

void glGetProgramInfoLog(GLuint program, GLsizei maxLength,
                         GLsizei *length, GLchar *infoLog);

💖 PARAMETERS 💖

• program — specifies the program object whose information log is to be queried. This is the main character of the call 👑.
• maxLength — specifies the size of the character buffer for storing the returned information log. Gotta give it room to spill the tea 🫖.
• length — returns the length of the string returned in infoLog (excluding the null terminator). It's the receipts for how much actually got returned.
• infoLog — specifies an array of characters that is used to return the information log. This is where the lore lands ✨.

🦋 DESCRIPTION 🦋

glGetProgramInfoLog returns the information log for the specified program object. The information log for a program object is modified when the program object is linked or validated. The string that is returned will be null terminated — no cap.

glGetProgramInfoLog returns in infoLog as much of the information log as it can, up to a maximum of maxLength characters. The number of characters actually returned, excluding the null termination character, is specified by length. If the length of the returned string is not required, a value of NULL can be passed in the length argument. The size of the buffer required to store the returned information log can be obtained by calling glGetProgram() with the value GL_INFO_LOG_LENGTH.

The information log for a program object is either an empty string, or a string containing information about the last link operation, or a string containing information about the last validation operation. It may contain diagnostic messages, warning messages, and other information. When a program object is created, its information log will be a string of length 0. Literally starts empty, bestie 🫶.

🌸 NOTES 🌸

Real talk: the information log for a program object is the OpenGL implementer's primary mechanism for conveying information about linking and validating. So the info log can be helpful to application developers during the development process, even when these operations are successful — yes, even the slayful successful ones 💅. Application developers should not expect different OpenGL implementations to produce identical information logs, periodt. Different implementations, different vibes.

💀 ERRORS 💀

• GL_INVALID_VALUE is generated if program is not a value generated by OpenGL. 🚩
• GL_INVALID_OPERATION is generated if program is not a program object. 😭
• GL_INVALID_VALUE is generated if maxLength is less than 0. 💀

🔥 ASSOCIATED GETS 🔥

• glGetProgram() with argument GL_INFO_LOG_LENGTH
• glIsProgram()
