NAME"glGetTexEnvfv, glGetTexEnviv − return texture environment parameters

---

C SPECIFICATIONvoid glGetTexEnvfv( GLenum target, GLenum pname, GLfloat *params )void glGetTexEnviv( GLenum target, GLenum pname, GLint *params )

---

PARAMETERStarget  Specifies a texture environment. Must be ­GL_TEXTURE_ENV. pname  Specifies the symbolic name of a texture environment parameter. Accepted values are ­GL_TEXTURE_ENV_MODE and ­GL_TEXTURE_ENV_COLOR. params  Returns the requested data.

---

DESCRIPTION­glGetTexEnv returns in params selected values of a texture environment that was specified with ­glTexEnv. target specifies a texture environment. Currently, only one texture environment is defined and supported: ­GL_TEXTURE_ENV. pname names a specific texture environment parameter, as follows: ­GL_TEXTURE_ENV_MODE  params returns the single-valued texture environment mode, a symbolic constant. The initial value is ­GL_MODULATE. ­GL_TEXTURE_ENV_COLOR  params returns four integer or floating-point values that are the texture environment color. Integer values, when requested, are linearly mapped from the internal floating-point representation such that 1.0 maps to the most positive representable integer, and −1.0 maps to the most negative representable integer. The initial value is (0, 0, 0, 0).

---

NOTESIf an error is generated, no change is made to the contents of params. When the ­GL_ARB_multitexture extension is supported, ­glGetTexEnv returns the texture environment parameters for the active texture unit.

---

ERRORS­GL_INVALID_ENUM is generated if target or pname is not an accepted value. ­GL_INVALID_OPERATION is generated if ­glGetTexEnv is executed between the execution of ­glBegin and the corresponding execution of ­glEnd.
