STRCASECMP(3) BSD Programmer's Manual STRCASECMP(3)NAME
strcasecmp, strncasecmp - compare strings, ignoring case
SYNOPSIS
#include <string.h>
int
strcasecmp(const char *s1, const char *s2);
int
strncasecmp(const char *s1, const char *s2, size_t len);
DESCRIPTION
The strcasecmp() and strncasecmp() functions compare the NUL-terminated
strings s1 and s2 and return an integer greater than, equal to, or less
than 0, according to whether s1 is lexicographically greater than, equal
to, or less than s2 after translation of each corresponding character to
lower-case. The strings themselves are not modified. The comparison is
done using unsigned characters, so that '\200' is greater than '\0'.
strncasecmp() compares at most len characters.
