GLGETSHADERSOURCE(3G)						   OpenGL Manual					     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.

NAME

       glShaderSource - Replaces the source code in a shader object

C SPECIFICATION

       void glShaderSource(GLuint shader, GLsizei count, const GLchar **string, const GLint *length);

PARAMETERS

       shader
	   Specifies the handle of the shader object whose source code is to be replaced.

       count
	   Specifies the number of elements in the string and length arrays.

       string
	   Specifies an array of pointers to strings containing the source code to be loaded into the shader.

       length
	   Specifies an array of string lengths.

DESCRIPTION

       glShaderSource sets the source code in shader to the source code in the array of strings specified by string. Any source code previously
       stored in the shader object is completely replaced. The number of strings in the array is specified by count. If length is NULL, each
       string is assumed to be null terminated. If length is a value other than NULL, it points to an array containing a string length for each of
       the corresponding elements of string. Each element in the length array may contain the length of the corresponding string (the null
       character is not counted as part of the string length) or a value less than 0 to indicate that the string is null terminated. The source
       code strings are not scanned or parsed at this time; they are simply copied into the specified shader object.

NOTES

       OpenGL copies the shader source code strings when glShaderSource is called, so an application may free its copy of the source code strings
       immediately after the function returns.

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 count is less than 0.
