This document is a Mac OS X manual page. Manual pages are a command-line technology for providing documentation. You can view these manual pages locally using the man(1) command. These manual pages come from many different sources, and thus, have a variety of writing styles. For more information about the manual page format, see the manual page for manpages(5). |
STRING(3) BSD Library Functions Manual STRING(3) NAME index, rindex, stpcpy, strcasecmp, strcat, strchr, strcmp, strcpy, strcspn, strerror, strlen, strncasecmp, strncat, strncmp, strncpy, strpbrk, strrchr, strsep, strspn, strstr, strtok -- string specific func-tions functions tions LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <strings.h> char * index(const char *s, int c); char * rindex(const char *s, int c); int strcasecmp(const char *s1, const char *s2); int strncasecmp(const char *s1, const char *s2, size_t n); #include <string.h> char * stpcpy(char *dst, const char *src); char * strcat(char *restrict s1, const char *restrict s2); char * strchr(const char *s, int c); int strcmp(const char *s1, const char *s2); char * strcpy(char *restrict s1, const char *restrict s2); size_t strcspn(const char *s1, const char *s2); char * strerror(int errnum); size_t strlen(const char *s); char * strncat(char *restrict s1, const char *restrict s2, size_t n); int strncmp(const char *s1, const char *s2, size_t n); char * strncpy(char *restrict s1, const char *restrict s2, size_t n); char * strpbrk(const char *s1, const char *s2); char * strrchr(const char *s, int c); char * strsep(char **stringp, const char *delim); size_t strspn(const char *s1, const char *s2); char * strstr(const char *s1, const char *s2); char * strtok(char *restrict s1, const char *restrict s2); DESCRIPTION The string functions manipulate strings that are terminated by a null byte. See the specific manual pages for more information. For manipulating variable length generic objects as byte strings (without the null byte check), see bstring(3). Except as noted in their specific manual pages, the string functions do not test the destination for size limitations.
