string.h - string operations
#include <string.h>
The <string.h> header defines the following:
- NULL
- Null pointer constant.
- size_t
- As described in <stddef.h>.
The following are declared as functions and may also be defined as macros. Function prototypes must be provided for use with an ISO C compiler.
void *memccpy(void *, const void *, int, size_t); void *memchr(const void *, int, size_t); int memcmp(const void *, const void *, size_t); void *memcpy(void *, const void *, size_t); void *memmove(void *, const void *, size_t); void *memset(void *, int, size_t); char *strcat(char *, const char *); char *strchr(const char *, int); int strcmp(const char *, const char *); int strcoll(const char *, const char *); char *strcpy(char *, const char *); size_t strcspn(const char *, const char *); char *strdup(const char *); char *strerror(int); size_t strlen(const char *); char *strncat(char *, const char *, size_t); int strncmp(const char *, const char *, size_t); char *strncpy(char *, const char *, size_t); char *strpbrk(const char *, const char *); char *strrchr(const char *, int); size_t strspn(const char *, const char *); char *strstr(const char *, const char *); char *strtok(char *, const char *); char *strtok_r(char *, const char *, char **); size_t strxfrm(char *, const char *, size_t);
Inclusion of the <string.h> header may also make visible all symbols from <stddef.h>.
