Parameters
Variables | Description |
---|---|
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.
