Reads a code-set map file and assigns it to the standard input device.
Standard C Library (libc.a)
#include <sys/termios.h>int setcsmap (Path);
char * Path;
The setcsmap subroutine reads in a code-set map file. The path parameter specifies the location of the code-set map file. The path is usually composed by forming a string with the csmap directory and the code set, as in the following example:
n=sprintf(path,"%s%s",CSMAP_DIR,nl_langinfo(CODESET));The file is processed and according to the included informations, the setcsmap subroutine changes the tty configuration. Multibyte processing may be enabled, and converter modules may be pushed onto the tty stream.
