GLGETPROGRAMINFOLOG(3G) 					    OpenGL 3.3						   GLGETPROGRAMINFOLOG(3G)

NAME

       glGetProgramInfoLog - Returns the information log for a program object

C SPECIFICATION

       void glGetProgramInfoLog(GLuint program, GLsizei maxLength, GLsizei *length, GLchar *infoLog);

PARAMETERS

       program
	   Specifies the program object whose information log is to be queried.

       maxLength
	   Specifies the size of the character buffer for storing the returned information log.

       length
	   Returns the length of the string returned in infoLog (excluding the null terminator).

       infoLog
	   Specifies an array of characters that is used to return the information log.

DESCRIPTION

       glGetProgramInfoLog returns the information log for the specified program object. The information log for a program object is modified when
       the program object is linked or validated. The string that is returned will be null terminated.

       glGetProgramInfoLog returns in infoLog as much of the information log as it can, up to a maximum of maxLength characters. The number of
       characters actually returned, excluding the null termination character, is specified by length. If the length of the returned string is not
       required, a value of NULL can be passed in the length argument. The size of the buffer required to store the returned information log can
       be obtained by calling glGetProgram() with the value GL_INFO_LOG_LENGTH.

       The information log for a program object is either an empty string, or a string containing information about the last link operation, or a
       string containing information about the last validation operation. It may contain diagnostic messages, warning messages, and other
       information. When a program object is created, its information log will be a string of length 0.

NOTES

       The information log for a program object is the OpenGL implementer's primary mechanism for conveying information about linking and
       validating. Therefore, the information log can be helpful to application developers during the development process, even when these
       operations are successful. Application developers should not expect different OpenGL implementations to produce identical information logs.

ERRORS

       GL_INVALID_VALUE is generated if program is not a value generated by OpenGL.

       GL_INVALID_OPERATION is generated if program is not a program object.

       GL_INVALID_VALUE is generated if maxLength is less than 0.

ASSOCIATED GETS

       glGetProgram() with argument GL_INFO_LOG_LENGTH

       glIsProgram()

GLGETPROGRAMPIPELINE(3G)					  [FIXME: manual]					  GLGETPROGRAMPIPELINE(3G)

NAME

       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.
