glGetShaderiv — Returns a parameter from a shader object
void glGetShaderiv(
|
GLuint shader, |
| GLenum pname, | |
GLint *params); |
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.
glGetShaderiv
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_TESS_CONTROL_SHADER if
shader is a tesselation control shader
object,GL_TESS_EVALUATION_SHADER if
shader is a tesselation evaluation shader
object,GL_GEOMETRY_SHADER if
shader is a geometry shader
object, GL_FRAGMENT_SHADER
if shader is a fragment
shader, and GL_COMPUTE_SHADER
if shader is a compute
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.
If an error is generated, no change is made to the
contents of params.
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.
