Name
glGenSamplers — generate sampler object names
C Specification
void glGenSamplers( |
GLsizei n, |
| |
GLuint *samplers); |
Parameters
n
Specifies the number of sampler object names to generate.
samplers
Specifies an array in which the generated sampler object names are stored.
Description
glGenSamplers returns n sampler object names in samplers. There is no guarantee that the names form a contiguous set of integers; however, it is guaranteed that none of the returned names was in use immediately before the call to glGenSamplers.
Sampler object names returned by a call to glGenSamplers are not returned by subsequent calls, unless they are first deleted with glDeleteSamplers.
The names returned in samplers are marked as used, for the purposes of glGenSamplers only, but they acquire state and type only when they are first bound.
Notes
glGenSamplers is available only if the GL version is 3.3 or higher.
Errors
GL_INVALID_VALUE is generated if n is negative.
