byte_chr - search for a byte in a string SYNTAX
#include <byte.h> size_t byte_chr(const char *haystack,size_t len,char needle); DESCRIPTION
byte_chr returns the smallest integer i between 0 and len-1 inclusive such that one[i] equals needle. If no such integer exists, byte_chr returns len. byte_chr may read all bytes one[0], one[1], ..., one[len-1], even if not all the bytes are relevant to the answer. SEE ALSO

STRSTR(3) BSD Library Functions Manual STRSTR(3) NAME
strstr, strcasestr, strnstr -- locate a substring in a string LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <string.h> char * strstr(const char *haystack, const char *needle); char * strcasestr(const char *haystack, const char *needle); char * strnstr(const char *haystack, const char *needle, size_t len); #include <string.h> #include <xlocale.h> char * strcasestr_l(const char *haystack, const char *needle, locale_t loc); DESCRIPTION
The strstr() function locates the first occurrence of the null-terminated string needle in the null-terminated string haystack. The strcasestr() function is similar to strstr(), but ignores the case of both strings. The strnstr() function locates the first occurrence of the null-terminated string needle in the string haystack, where not more than len characters are searched. Characters that appear after a '
