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.
