string(5)                                                         string(5)

NAME
     string - string operations

SYNOPSIS
     #include <string.h>

DESCRIPTION
     The <string.h> header defines the following:

     NULL        Null pointer constant.

     sizet      As described in <stddef.h>.

     The following are declared as functions and may also be defined as
     macros:

     void   *memccpy(void *s1, const void *s2, int c, sizet n);
     void   *memchr(const void *s, int c, sizet n);
     int     memcmp(const void *s1, const void *s2, sizet n);
     void   *memcpy(void *s1, const void *s2, sizet n);
     void   *memmove(void *s1, const void *s2, sizet n);
     void   *memset(void *s, int c, sizet n);
     char   *strcat(char *s1, const char *s2);
     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 *s1, const char *s2);
     sizet  strcspn(const char *s1, const char *s2);
     char   *strdup(const char *s1);
     char   *strerror(int errnum);
     sizet  strlen(const char *s);
     char   *strncat(char *s1, const char *s2, sizet n);
     int     strncmp(const char *s1, const char *s2, sizet n);
     char   *strncpy(char *s1, const char *s2, sizet n);
     char   *strpbrk(const char *s1, const char *s2);
     char   *strrchr(const char *s, int c);
     sizet  strspn(const char *s1, const char *s2);
     char   *strstr(const char *s1, const char *s2);
     char   *strtok(char *s1, const char *s2);
     sizet  strxfrm(char *s1, const char *s2, sizet n);

     Inclusion of the <string.h> header may also make visible all symbols
     from <stddef.h>.
