GLBINDSAMPLERS(3G)

NAME
glBindSamplers - bind one or more named sampler objects to a sequence of consecutive sampler units

C SPECIFICATION

void glBindSamplers(GLuint first, GLsizei count, const GLuint *samplers);

PARAMETERS

first
    Specifies the first sampler unit to which a sampler object is to be bound.

count
    Specifies the number of samplers to bind.

samplers
    Specifies the address of an array of names of existing sampler objects.

DESCRIPTION

glBindSamplers binds samplers from an array of existing sampler objects to a specified number of consecutive sampler units. count specifies the number of sampler objects whose names are stored in the array samplers. That number of sampler names is read from the array and bound to the count consecutive sampler units starting from first.

If the name zero appears in the samplers array, any existing binding to the sampler unit is reset. Any non-zero entry in samplers must be the name of an existing sampler object. When a non-zero entry in samplers is present, that sampler object is bound to the corresponding sampler unit. If samplers is NULL then it is as if an appropriately sized array containing only zeros had been specified.

glBindSamplers is equivalent to the following pseudo code:

        for (i = 0; i < count; i++) {
            if (samplers == NULL) {
                glBindSampler(first + i, 0);
            } else {
                glBindSampler(first + i, samplers[i]);
            }
        }

Each entry in samplers will be checked individually and if found to be invalid, the state for that sampler unit will not be changed and an error will be generated. However, the state for other sampler units referenced by the command will still be updated.

NOTES

glBindSamplers is available only if the GL version is 4.4 or higher.

ERRORS

GL_INVALID_OPERATION is generated if first + count is greater than the number of sampler units supported by the implementation.

GL_INVALID_OPERATION is generated if any value in samplers is not zero or the name of an existing sampler object.
