GLGETSHADERSOURCE(3G)						    OpenGL 3.3						     GLGETSHADERSOURCE(3G)

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()

NAME

       glGetShaderiv - Returns a parameter from a shader object

C SPECIFICATION

       void glGetShaderiv(GLuint shader, GLenum pname, GLint *params);

PARAMETERS

       shader
	   Specifies the shader object to be queried.

       pname
	   Specifies the object parameter. Accepted symbolic names are GL_SHADER_TYPE, GL_DELETE_STATUS, GL_COMPILE_STATUS, GL_INFO_LOG_LENGTH,
	   GL_SHADER_SOURCE_LENGTH.

       params
	   Returns the requested object parameter.

DESCRIPTION

       glGetShader returns in params the value of a parameter for a specific shader object. The following parameters are defined:

       GL_SHADER_TYPE

	   params returns GL_VERTEX_SHADER if shader is a vertex shader object, GL_GEOMETRY_SHADER if shader is a geometry shader object, and
	   GL_FRAGMENT_SHADER if shader is a fragment shader object.

       GL_DELETE_STATUS

	   params returns GL_TRUE if shader is currently flagged for deletion, and GL_FALSE otherwise.

       GL_COMPILE_STATUS

	   params returns GL_TRUE if the last compile operation on shader was successful, and GL_FALSE otherwise.

       GL_INFO_LOG_LENGTH

	   params returns the number of characters in the information log for shader including the null termination character (i.e., the size of
	   the character buffer required to store the information log). If shader has no information log, a value of 0 is returned.

       GL_SHADER_SOURCE_LENGTH

	   params returns the length of the concatenation of the source strings that make up the shader source for the shader, including the null
	   termination character. (i.e., the size of the character buffer required to store the shader source). If no source code exists, 0 is
	   returned.

NOTES

       If an error is generated, no change is made to the contents of params.

ERRORS

       GL_INVALID_VALUE is generated if shader is not a value generated by OpenGL.

       GL_INVALID_OPERATION is generated if shader does not refer to a shader object.

       GL_INVALID_ENUM is generated if pname is not an accepted value.

ASSOCIATED GETS

       glGetShaderSource() with argument shader

       glIsShader()
