NAME

       glGetShaderInfoLog - Returns the information log for a shader object

C SPECIFICATION

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

PARAMETERS

       shader
           Specifies the shader object whose information log is to be queried.

       maxLength
           Specifies the size of the character buffer for storing the returned information log.

       length
           Returns the length of the string returned in infoLog (excluding the null terminator).

       infoLog
           Specifies an array of characters that is used to return the information log.

DESCRIPTION

       glGetShaderInfoLog returns the information log for the specified shader object. The information log for a
       shader object is modified when the shader is compiled. The string that is returned will be null
       terminated.

       glGetShaderInfoLog 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 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.

NOTES

       The information log for a shader object is the OpenGL implementer's primary mechanism for conveying
       information about the compilation process. Therefore, the information log 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.

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()
