man glGetQueryIndexediv (3): 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_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

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.
