#include <strings.h>
- int strcasecmp(const char *s1, const char
*s2);
- Compare the strings s1 and s2 ignoring case.
- int strncasecmp(const char *s1, const char
*s2, size_t n);
- Compare the first n bytes of the strings s1 and s2
ignoring case.
- char *index(const char *s, int c);
- Return a pointer to the first occurrence of the character c in the
string s.
- char *rindex(const char *s, int
c);
- Return a pointer to the last occurrence of the character c in the
string s.
- #include <string.h>
- char *stpcpy(char *dest, const char
*src);
- Copy a string from src to dest, returning a pointer to the
end of the resulting string at dest.
- char *strcat(char *dest, const char
*src);
- Append the string src to the string dest, returning a
pointer dest.
- char *strchr(const char *s, int
c);
- Return a pointer to the first occurrence of the character c in the
string s.
- int strcmp(const char *s1, const char
*s2);
- Compare the strings s1 with s2.
- int strcoll(const char *s1, const char
*s2);
- Compare the strings s1 with s2 using the current
locale.
- char *strcpy(char *dest, const char
*src);
- Copy the string src to dest, returning a pointer to the
start of dest.
- size_t strcspn(const char *s, const char
*reject);
- Calculate the length of the initial segment of the string s which
does not contain any of bytes in the string reject,
- char *strdup(const char *s);
- Return a duplicate of the string s in memory allocated using
malloc(3).
- char *strfry(char *string);
- Randomly swap the characters in string.
- size_t strlen(const char *s);
- Return the length of the string s.
- char *strncat(char *dest, const char *src,
size_t n);
- Append at most n bytes from the string src to the string
dest, returning a pointer to dest.
- int strncmp(const char *s1, const char *s2,
size_t n);
- Compare at most n bytes of the strings s1 and
s2.
- char *strncpy(char *dest, const char *src,
size_t n);
- Copy at most n bytes from string src to dest,
returning a pointer to the start of dest.
- char *strpbrk(const char *s, const char
*accept);
- Return a pointer to the first occurrence in the string s of one of
the bytes in the string accept.
- char *strrchr(const char *s, int
c);
- Return a pointer to the last occurrence of the character c in the
string s.
- char *strsep(char **stringp, const char
*delim);
- Extract the initial token in stringp that is delimited by one of
the bytes in delim.
- size_t strspn(const char *s, const char
*accept);
- Calculate the length of the starting segment in the string s that
consists entirely of bytes in accept.
- char *strstr(const char *haystack, const char
*needle);
- Find the first occurrence of the substring needle in the string
haystack, returning a pointer to the found substring.
- char *strtok(char *s, const char
*delim);
- Extract tokens from the string s that are delimited by one of the
bytes in delim.
- size_t strxfrm(char *dest, const char *src,
size_t n);
- Transforms src to the current locale and copies the first n
bytes to dest.
The string functions perform operations on null-terminated strings. See the
individual man pages for descriptions of each function.
