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.
