/Tc, /Tp, /TC, /TP (Specify Source File Type)

/Tcfilename
/Tpfilename
/TC
/TP

where:

filename
A C or C++ source file.

Remarks

The /Tc option specifies that filename is a C source file, even if it doesn't have a .c extension. The /Tp option specifies that filename is a C++ source file, even if it doesn't have a .cpp or .cxx extension. A space between the option and filename is optional. Each option specifies one file; to specify additional files, repeat the option.

/TC and /TP are "global" variants of /Tc and /Tp. They specify to the compiler to treat all files named on the command line as C source files (/TC) or C++ source files (/TP), without regard to location on the command line in relation to the option. These global options can be overridden on a single file via /Tc or /Tp.

By default, CL assumes that files with the .c extension are C source files and files with the .cpp or the .cxx extension are C++ source files.

To set this compiler option in the Visual Studio development environment

  1. Open the project's Property Pages dialog box. For details, see Setting Visual C++ Project Properties.
  2. Click the C/C++ folder.
  3. Click the Advanced property page.
  4. Modify the Compile As property.

To set this compiler option programmatically

See CompileAs Property.

Examples

The following CL command line specifies that MAIN.c, TEST.prg, and COLLATE.prg are all C source files. CL will not recognize PRINT.prg.

CL MAIN.C /TcTEST.PRG /TcCOLLATE.PRG PRINT.PRG

The following CL command line specifies that TEST1.c, TEST2.cxx, TEST3.huh, and TEST4.o are compiled as C++ files, and TEST5.z is compiled as a C file.

CL TEST1.C TEST2.CXX TEST3.HUH TEST4.O /Tc TEST5.Z /TP
