ПРОЛОГ

       This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

СИНТАКСИС

       #include <string.h>

ОПИСАНИЕ

       Some of the functionality described on this reference page
       extends the ISO C standard. Applications shall define the
       appropriate feature test macro (see the System Interfaces volume
       of POSIX.1‐2017, Section 2.2, The Compilation Environment) to
       enable the visibility of these symbols in this header.

       The <string.h> header shall define NULL and size_t as described
       in <stddef.h>.

       The <string.h> header shall define the locale_t type as described
       in <locale.h>.

       The following shall be declared as functions and may also be
       defined as macros. Function prototypes shall be provided for use
       with ISO C standard compilers.

           void    *memccpy(void *restrict, const void *restrict, int, size_t);
           void    *memchr(const void *, int, size_t);
           int      memcmp(const void *, const void *, size_t);
           void    *memcpy(void *restrict, const void *restrict, size_t);
           void    *memmove(void *, const void *, size_t);
           void    *memset(void *, int, size_t);
           char    *stpcpy(char *restrict, const char *restrict);
           char    *stpncpy(char *restrict, const char *restrict, size_t);
           char    *strcat(char *restrict, const char *restrict);
           char    *strchr(const char *, int);
           int      strcmp(const char *, const char *);
           int      strcoll(const char *, const char *);
           int      strcoll_l(const char *, const char *, locale_t);
           char    *strcpy(char *restrict, const char *restrict);
           size_t   strcspn(const char *, const char *);
           char    *strdup(const char *);
           char    *strerror(int);
           char    *strerror_l(int, locale_t);
           int      strerror_r(int, char *, size_t);
           size_t   strlen(const char *);
           char    *strncat(char *restrict, const char *restrict, size_t);
           int      strncmp(const char *, const char *, size_t);
           char    *strncpy(char *restrict, const char *restrict, size_t);
           char    *strndup(const char *, size_t);
           size_t   strnlen(const char *, size_t);
           char    *strpbrk(const char *, const char *);
           char    *strrchr(const char *, int);
           char    *strsignal(int);
           size_t   strspn(const char *, const char *);
           char    *strstr(const char *, const char *);
           char    *strtok(char *restrict, const char *restrict);
           char    *strtok_r(char *restrict, const char *restrict, char **restrict);
           size_t   strxfrm(char *restrict, const char *restrict, size_t);
           size_t   strxfrm_l(char *restrict, const char *restrict,
                        size_t, locale_t);

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