LIBRARY

Standard C library (libc, -lc)

SYNOPSIS

#include <strings.h>

Compare the strings s1 and s2 ignoring case.
Compare the first n bytes of the strings s1 and s2 ignoring case.
Return a pointer to the first occurrence of the character c in the string s.
Return a pointer to the last occurrence of the character c in the string s.
#include <string.h>
Copy a string from src to dest, returning a pointer to the end of the resulting string at dest.
Append the string src to the string dest, returning a pointer dest.
Return a pointer to the first occurrence of the character c in the string s.
Compare the strings s1 with s2.
Compare the strings s1 with s2 using the current locale.
Copy the string src to dest, returning a pointer to the start of dest.
Calculate the length of the initial segment of the string s which does not contain any of bytes in the string reject,
Return a duplicate of the string s in memory allocated using malloc(3).
Randomly swap the characters in string.
Return the length of the string s.
Append at most n bytes from the string src to the string dest, returning a pointer to dest.
Compare at most n bytes of the strings s1 and s2.
Copy at most n bytes from string src to dest, returning a pointer to the start of dest.
Return a pointer to the first occurrence in the string s of one of the bytes in the string accept.
Return a pointer to the last occurrence of the character c in the string s.
Extract the initial token in stringp that is delimited by one of the bytes in delim.
Calculate the length of the starting segment in the string s that consists entirely of bytes in accept.
Find the first occurrence of the substring needle in the string haystack, returning a pointer to the found substring.
Extract tokens from the string s that are delimited by one of the bytes in delim.
Transforms src to the current locale and copies the first n bytes to dst.

DESCRIPTION

The string functions perform operations on null-terminated strings. See the individual man pages for descriptions of each function.
