Informix Error -16375: Cannot view C-library function function-name.

Cause and resolution

Cannot view C-library function function-name.

The VIEW command cannot display the source code of C functions or ESQL/C functions. To examine C source code, you must use the Escape feature and use an operating-system command that displays the C source file.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-16375 fires when VIEW targets a C or ESQL/C function — per the official guidance. VIEW can't display source code for functions not written in 4GL.

  1. VIEW targeting a C/ESQL/C function, per the official guidance — the direct, only cause.
Solutions / Resolution
  1. Use the Escape feature and an operating-system command to display the C source file, per the official guidance, instead of VIEW.
Examples
N/A

No specific triggering statement is documented beyond VIEW targeting a C function.

Diagnostic Checks
  1. Check whether the target function is written in 4GL, and use an OS-level file viewer for C/ESQL/C source instead of VIEW.
