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.
Имя (Name)
string.h — string operations
Синопсис (Synopsis)
#include <string.h>
Описание (Description)
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>.
