NAME

       glObjectLabel - label a named object identified within a namespace

C SPECIFICATION

       void glObjectLabel(GLenum identifier, GLuint name, GLsizei length, const char * label);

PARAMETERS

       identifier
	   The namespace from which the name of the object is allocated.

       name
	   The name of the object to label.

       length
	   The length of the label to be used for the object.

       label
	   The address of a string containing the label to assign to the object.

DESCRIPTION

       glObjectLabel labels the object identified by name within the namespace given by identifier.  identifier must be one of GL_BUFFER,
       GL_SHADER, GL_PROGRAM, GL_VERTEX_ARRAY, GL_QUERY, GL_PROGRAM_PIPELINE, GL_TRANSFORM_FEEDBACK, GL_SAMPLER, GL_TEXTURE, GL_RENDERBUFFER,
       GL_FRAMEBUFFER, to indicate the namespace containing the names of buffers, shaders, programs, vertex array objects, query objects, program
       pipelines, transform feedback objects, samplers, textures, renderbuffers and frame buffers, respectively.

       label is the address of a string that will be used to label an object.  length contains the number of characters in label. If length is
       negative, it is implied that label contains a null-terminated string. If label is NULL, any debug label is effectively removed from the
       object.

ERRORS

       GL_INVALID_ENUM is generated if identifier is not one of the accepted object types.

       GL_INVALID_OPERATION is generated if name is not the name of an existing object of the type specified by identifier.

       GL_INVALID_VALUE is generated if the number of characters in label, excluding the null terminator when length is negative, is greater than
       the value of GL_MAX_LABEL_LENGTH.

ASSOCIATED GETS

       glGet() with argument GL_MAX_LABEL_LENGTH.

NAME

       glGetShaderSource - Returns the source code string from a shader object

C SPECIFICATION

       void glGetShaderSource(GLuint shader, GLsizei bufSize, GLsizei *length, GLchar *source);

PARAMETERS

       shader
	   Specifies the shader object to be queried.

       bufSize
	   Specifies the size of the character buffer for storing the returned source code string.

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

       source
	   Specifies an array of characters that is used to return the source code string.

DESCRIPTION

       glGetShaderSource returns the concatenation of the source code strings from the shader object specified by shader. The source code strings
       for a shader object are the result of a previous call to glShaderSource(). The string returned by the function will be null terminated.

       glGetShaderSource returns in source as much of the source code string as it can, up to a maximum of bufSize 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 source code string
       can be obtained by calling glGetShader() with the value GL_SHADER_SOURCE_LENGTH.

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 bufSize is less than 0.

ASSOCIATED GETS

       glGetShader() with argument GL_SHADER_SOURCE_LENGTH

       glIsShader()
