case_starts(3) Library Functions Manual case_starts(3)NAME
case_starts - compare prefixes of strings case-insensitively
SYNTAX
#include <case.h>
int case_starts(const char* a,const char* b);
DESCRIPTION
case_starts returns 1 if b is a prefix of a, 0 otherwise. For this comparison, 'A' == 'a', 'B' == 'b', ..., 'Z' == 'z'.

STRCASECMP(3) BSD Library Functions Manual STRCASECMP(3)NAME
strcasecmp, strcasecmp_l, strncasecmp, strncasecmp_l -- compare strings, ignoring case
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <strings.h>
int
strcasecmp(const char *s1, const char *s2);
int
strncasecmp(const char *s1, const char *s2, size_t n);
#include <strings.h>
#include <xlocale.h>
int
strcasecmp_l(const char *s1, const char *s2, locale_t loc);
int
strncasecmp_l(const char *s1, const char *s2, size_t n, locale_t loc);
DESCRIPTION
The strcasecmp() and strncasecmp() functions compare the null-terminated strings s1 and s2.
The strncasecmp() compares at most n characters.
Although the strcasecmp() and strncasecmp() functions use the current locale, the strcasecmp_l() and strncasecmp_l() functions may be passed
locales directly. See xlocale(3) for more information.
RETURN VALUES
The strcasecmp() and strncasecmp() 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 ' '.

The strcasecmp() and strncasecmp() functions first appeared in 4.4BSD. Their prototypes existed previously in <string.h> before they were
moved to <strings.h> for IEEE Std 1003.1-2001 (``POSIX.1'') compliance.
