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
.
