strncmp - compare part of two strings SYNOPSIS
#include <string.h> int strncmp(const char *s1, const char *s2, size_t n); DESCRIPTION
The strncmp() function shall compare not more than n bytes (bytes that follow a null byte are not compared) from the array pointed to by s1 to the array pointed to by s2. The sign of a non-zero return value is determined by the sign of the difference between the values of the first pair of bytes (both inter- preted as type unsigned char) that differ in the strings being compared. RETURN VALUE
Upon successful completion, strncmp() shall return an integer greater than, equal to, or less than 0, if the possibly null-terminated array pointed to by s1 is greater than, equal to, or less than the possibly null-terminated array pointed to by s2 respectively. ERRORS
No errors are defined. The following sections are informative. EXAMPLES
None. APPLICATION USAGE
None. RATIONALE
None. FUTURE DIRECTIONS

wcsncmp - compare part of two wide-character strings SYNOPSIS
#include <wchar.h> int wcsncmp(const wchar_t *ws1, const wchar_t *ws2, size_t n); DESCRIPTION
The wcsncmp() function shall compare not more than n wide-character codes (wide-character codes that follow a null wide-character code are not compared) from the array pointed to by ws1 to the array pointed to by ws2. The sign of a non-zero return value shall be determined by the sign of the difference between the values of the first pair of wide-charac- ter codes that differ in the objects being compared. RETURN VALUE
Upon successful completion, wcsncmp() shall return an integer greater than, equal to, or less than 0, if the possibly null-terminated array pointed to by ws1 is greater than, equal to, or less than the possibly null-terminated array pointed to by ws2, respectively. ERRORS
