PC-lint, developed by Gimpel Software, is a static analysis tool for checking C and C++ source code. The lph file extension identifies files containing precompiled header data used by the analyzer.
An lph file belongs to PC-lint's internal working files rather than to the source project itself. PC-lint can reuse the stored header information during analysis, reducing the need to process the same headers repeatedly.
PC-lint for C/C++ is available on multiple platforms, including Microsoft Windows. The lph format is intended for use by PC-lint and is not a general-purpose document format.
Open an lph file with PC-lint for C/C++, which creates and reads it as part of its precompiled-header processing. It is not intended to be opened or edited manually in a text editor or standalone viewer.
An lph file is an internal PC-lint precompiled-header file and has no useful standalone conversion format. If necessary, PC-lint can recreate the file from the relevant source and header configuration instead of converting it.
