Name: instr
Synopsis:
int instr(char *str);
int innstr(char *str, int n);
int winstr(WINDOW *win, char *str);
int winnstr(WINDOW *win, char *str, int n);
int mvinstr(int y, int x, char *str);
int mvinnstr(int y, int x, char *str, int n);
int mvwinstr(WINDOW *win, int y, int x, char *str);
int mvwinnstr(WINDOW *win, int y, int x, char *str, int n);
int inwstr(wchar_t *wstr);
int innwstr(wchar_t *wstr, int n);
int winwstr(WINDOW *win, wchar_t *wstr);
int winnwstr(WINDOW *win, wchar_t *wstr, int n);
int mvinwstr(int y, int x, wchar_t *wstr);
int mvinnwstr(int y, int x, wchar_t *wstr, int n);
int mvwinwstr(WINDOW *win, int y, int x, wchar_t *wstr);
int mvwinnwstr(WINDOW *win, int y, int x, wchar_t *wstr, int n);
Description:
These functions take characters (or wide characters) from the
current or specified position in the window, and return them as
a string in str (or wstr). Attributes are ignored. The functions
with n as the last argument return a string at most n characters
long.
Return Value:
Upon successful completion, innstr(), mvinnstr(), mvwinnstr()
and winnstr() return the number of characters actually read into
the string; instr(), mvinstr(), mvwinstr() and winstr() return
OK. Otherwise, all these functions return ERR.
