glGenQueries - OpenGL 4 Reference Pages

## 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.

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
