本文详细介绍了Linux环境下的一系列字符串操作函数，包括strcat,strchr,strcmp等，并提供了这些函数的基本用法及说明。通过本文，读者可以了解如何在C语言中有效使用这些字符串处理函数。

STRING(3) Linux Programmer?. Manual STRING(3)

NAME
       strcasecmp, strcat, strchr, strcmp, strcoll, strcpy, strcspn, strdup,
       strfry, strlen, strncat, strncmp, strncpy, strncasecmp, strpbrk, str-
       rchr, strsep, strspn, strstr, strtok, strxfrm, index, rindex - string
       operations

SYNOPSIS
#include <strings.h>

int strcasecmp(const char *s1, const char *s2);

int strncasecmp(const char *s1, const char *s2, size_t n);

char *index(const char *s, int c);

char *rindex(const char *s, int c);

#include <string.h>

char *strcat(char *dest, const char *src);

char *strchr(const char *s, int c);

int strcmp(const char *s1, const char *s2);

int strcoll(const char *s1, const char *s2);

char *strcpy(char *dest, const char *src);

size_t strcspn(const char *s, const char *reject);

char *strdup(const char *s);

char *strfry(char *string);

size_t strlen(const char *s);

char *strncat(char *dest, const char *src, size_t n);

int strncmp(const char *s1, const char *s2, size_t n);

char *strncpy(char *dest, const char *src, size_t n);

char *strpbrk(const char *s, const char *accept);

char *strrchr(const char *s, int c);

char *strsep(char **stringp, const char *delim);

size_t strspn(const char *s, const char *accept);

char *strstr(const char *haystack, const char *needle);

char *strtok(char *s, const char *delim);

size_t strxfrm(char *dest, const char *src, size_t n);

DESCRIPTION
       The string functions perform string operations on NUL-terminated
       strings.   See the individual man pages for descriptions of each func-
       tion.
