NAME¶
glGetShaderiv - Returns a parameter from a shader objectC SPECIFICATION¶
void glGetShaderiv(GLuint shader,
GLenum pname,
GLint *params);
PARAMETERS¶
shaderSpecifies 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_TYPEparams 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.ASSOCIATED GETS¶
