# glGetProgramPipelineInfoLog

retrieve the info log string from a program pipeline object

## C Specification

                    void glGetProgramPipelineInfoLog
                    GLuint pipeline
                    GLsizei bufSize
                    GLsizei *length
                    GLchar *infoLog

## Parameters

`pipeline`

  Specifies the name of a program pipeline object from which to retrieve the info log.

`bufSize`

  Specifies the maximum number of characters, including the null terminator, that may be written into `infoLog`.

`length`

  Specifies the address of a variable into which will be written the number of characters written into `infoLog`.

`infoLog`

  Specifies the address of an array of characters into which will be written the info log for `pipeline`.

## Description

`glGetProgramPipelineInfoLog` retrieves the info log for the program pipeline object `pipeline`. The info log, including its null terminator, is written into the array of characters whose address is given by `infoLog`. The maximum number of characters that may be written into `infoLog` is given by `bufSize`, and the actual number of characters written into `infoLog` is returned in the integer whose address is given by `length`. If `length` is `NULL`, no length is returned.

The actual length of the info log for the program pipeline may be determined by calling glGetProgramPipeline with `pname` set to `GL_INFO_LOG_LENGTH`.

## Errors

`GL_INVALID_OPERATION` is generated if `pipeline` is not a name previously returned from a call to glGenProgramPipelines or if such a name has been deleted by a call to glDeleteProgramPipelines.

## Associated Gets

glGetProgramPipeline with parameter `GL_INFO_LOG_LENGTH`.

## API Version Support

`glGetProgramPipelineInfoLog`
