GLGETSHADER(3G) OpenGL 3.3 GLGETSHADER(3G) 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. ASSOCIATED GETS
