wcsncmp \- compare part of two wide-character strings
11
int wcsncmp(const wchar_t *\fP\fIws1\fP\fB, const wchar_t *\fP\fIws2\fP\fB,
12
size_t\fP \fIn\fP\fB);
17
The \fIwcsncmp\fP() function shall compare not more than \fIn\fP wide-character
18
codes (wide-character codes that follow a null
19
wide-character code are not compared) from the array pointed to by
20
\fIws1\fP to the array pointed to by \fIws2\fP.
22
The sign of a non-zero return value shall be determined by the sign
23
of the difference between the values of the first pair of
24
wide-character codes that differ in the objects being compared.
27
Upon successful completion, \fIwcsncmp\fP() shall return an integer
28
greater than, equal to, or less than 0, if the possibly
29
null-terminated array pointed to by \fIws1\fP is greater than, equal
30
to, or less than the possibly null-terminated array pointed
31
to by \fIws2\fP, respectively.
