STRCASECMP(3)

NAME
strcasecmp, strncasecmp, stricmp, strincmp - compare strings, ignoring case

SYNOPSIS
#include <string.h>

short stricmp (const char *s1, const char *s2);
short strincmp (const char *s1, const char *s2, unsigned n);
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 null-terminated strings s1 and s2 and return an integer greater than, equal to, or less than 0, according as 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.

The strncasecmp compares at most len characters.

stricmp and strincmp are functionally identically equal to, and implemented in terms of, strcasecmp and strncasecmp, respectively.
