# glGetProgramInfoLog

Definition: | include pGUI.e include opengl.e string res = glGetProgramInfoLog(integer shader)
Description: | return the information log for a program object program: Specifies the program object whose information log is to be queried.
pwa/p2js: | Supported.
Notes: | The opengl.e wrapper and pGUI.js take care of the required buffer automatically, you do not need to and in fact cannot provide your own temporary buffer (unlike the C api). 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. 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. 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.
