|
|
* 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.
