glGetShaderSource — Returns the source code string from a shader object
void glGetShaderSource( | GLuint shader, |
| GLsizei bufSize, | |
| GLsizei *length, | |
GLchar *source); |
shaderSpecifies the shader object to be queried.
bufSizeSpecifies the size of the character buffer for storing the returned source code string.
lengthReturns the length of the string returned in
source (excluding the null
terminator).
sourceSpecifies an array of characters that is used to return the source code string.
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.
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.
