_acmdln, _tcmdln, _wcmdln
Internal CRT global variable. The command line.
char * _acmdln; wchar_t * _wcmdln; #ifdef WPRFLAG #define _tcmdln _wcmdln #else #define _tcmdln _acmdln
These CRT internal variables store the complete command line. They are exposed in the exported symbols for the CRT, but are not intended for use in your code. _acmdln stores the data as a character string. _wcmdln stores the data as a wide character string. _tcmdln can be defined as either _acmdln or _wcmdln, depending on which is appropriate.
