glGetQueryIndexediv
3G
glGetQueryIndexediv
return parameters of an indexed query object target
C Specification
void glGetQueryIndexediv
GLenum target
GLuint index
GLenum pname
GLint * params
Parameters
target
Specifies a query object target.
Must be GL_SAMPLES_PASSED, GL_ANY_SAMPLES_PASSED, GL_ANY_SAMPLES_PASSED_CONSERVATIVE
GL_PRIMITIVES_GENERATED, GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN,
GL_TIME_ELAPSED, or GL_TIMESTAMP.
index
Specifies the index of the query object target.
pname
Specifies the symbolic name of a query object target parameter.
Accepted values are GL_CURRENT_QUERY or GL_QUERY_COUNTER_BITS.
params
Returns the requested data.
Description
glGetQueryIndexediv returns in params a selected parameter of the indexed query object target
specified by target and index. index specifies the index of the
query object target and must be between zero and a target-specific maxiumum.
pname names a specific query object target parameter. When pname is
GL_CURRENT_QUERY, the name of the currently active query for the specified index of target,
or zero if no query is active, will be placed in params.
If pname is GL_QUERY_COUNTER_BITS, the implementation-dependent number
of bits used to hold the result of queries for target is returned in params.
Notes
The target GL_ANY_SAMPLES_PASSED_CONSERVATIVE is available only if the GL version is 4.3 or greater.
If an error is generated,
no change is made to the contents of params.
Calling glGetQueryiv is equivalent to calling
glGetQueryIndexediv with index set to zero.
Errors
GL_INVALID_ENUM is generated if target or pname is not an
accepted value.
GL_INVALID_VALUE is generated if index is greater than or equal to the
target-specific maximum.
