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()
