Parameters
| Variables | Description |
|---|---|
| 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.
