NAME
glGetShaderiv - Returns a parameter from a shader object
C SPECIFICATION
-
void glGetShaderiv(GLuint shader, GLenum pname, GLint *params);
PARAMETERS
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.
DESCRIPTION
glGetShader
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_GEOMETRY_SHADER
if
shader
is a geometry shader object, and
GL_FRAGMENT_SHADER
if
shader
is a fragment 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.
NOTES
If an error is generated, no change is made to the contents of
params.
ERRORS
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.
