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.
