NAME¶
glProgramParameter - specify a parameter for a program object
C SPECIFICATION¶
void
glProgramParameteri(GLuint program,
GLenum pname, GLint value);
PARAMETERS¶
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.
DESCRIPTION¶
glProgramParameter 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.
ERRORS¶
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.
ASSOCIATED GETS¶
glGetProgram().
