glGenQueries

Name

glGenQueries — generate query object names

C Specification

void glGenQueries( GLsizei n,
  GLuint * ids);
 

Parameters

n

Specifies the number of query object names to be generated.

ids

Specifies an array in which the generated query object names are stored.

Description

glGenQueries returns n query object names in ids. 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 glGenQueries.

Query object names returned by a call to glGenQueries are not returned by subsequent calls, unless they are first deleted with glDeleteQueries.

The names returned in ids are marked as used, for the purposes of glGenQueries only, but no query objects are associated with the returned query object names until they are first used by calling glBeginQuery.

Errors

GL_INVALID_VALUE is generated if n is negative.

Associated Gets

glIsQuery
