glProgramParameteri — specify a parameter for a program object
void glProgramParameteri(
|
GLuint program, |
| GLenum pname, | |
GLint value); |
program
Specifies the name of a program object whose parameter to modify.
pname
Specifies the name of the parameter to modify.
value
Specifies the new value of the parameter specified by pname for program.
glProgramParameteri specifies a new value for the parameter nameed by
pname for the program object program.
If pname is
GL_PROGRAM_BINARY_RETRIEVABLE_HINT,
value should be
GL_FALSE or GL_TRUE to
indicate to the implementation the intention of the application
to retrieve the program's binary representation with
glGetProgramBinary.
The implementation may use this information to store information
that may be useful for a future query of the program's binary.
It is recommended to set
GL_PROGRAM_BINARY_RETRIEVABLE_HINT for the
program to GL_TRUE before calling
glLinkProgram,
and using the program at run-time if the binary is to be
retrieved later.
If pname is
GL_PROGRAM_SEPARABLE,
value must be
GL_TRUE or GL_FALSE
and indicates whether program can be
bound to individual pipeline stages via
glUseProgramStages.
A program's GL_PROGRAM_SEPARABLE parameter
must be set to GL_TRUE
before
glLinkProgram
is called in order for it to be usable with a program pipeline
object. The initial state of
GL_PROGRAM_SEPARABLE is
GL_FALSE.
GL_INVALID_OPERATION is generated if
program is not the name of an existing
program object.
GL_INVALID_ENUM is generated if
pname is not one of the accepted values.
GL_INVALID_VALUE is generated if
value is not a valid value for the
parameter named by pname.
