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

The /Tc option specifies that filename is a C source file, even if it does not 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 by means of /Tc or /Tp.

Arguments

Remarks

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.

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
