string(3) Library Functions Manual string(3)
stpcpy, strcasecmp, strcat, strchr, strcmp, strcoll, strcpy,
strcspn, strdup, strfry, strlen, strncat, strncmp, strncpy,
strncasecmp, strpbrk, strrchr, strsep, strspn, strstr, strtok,
strxfrm, index, rindex - string operations
Standard C library (libc, -lc)
#include <strings.h>
strcasecmp(3)
Compare two strings, ignoring case.
strncasecmp(3)
Compare the first bytes of two strings, ignoring case.
index(3)
Identical to strchr(3).
rindex(3)
Identical to strrchr(3).
#include <string.h>
stpcpy(3)
Copy a string, returning a pointer to the end of the
resulting string.
strcat(3)
Append a string into an existing string.
strchr(3)
Find the first occurrence of a character in a string.
strcmp(3)
Compare two strings.
strcoll(3)
Compare two strings, using the current locale.
strcpy(3)
Copy a string.
strcspn(3)
Calculate the length of the initial segment of a string
which does not contain any of the rejected bytes.
strdup(3)
Duplicate a string in memory allocated using malloc(3).
strfry(3)
Randomly swap the characters in a string.
strlen(3)
Return the length of a string.
strncat(3)
Append non-null bytes from an array to a string, and null-
terminate the result.
strncmp(3)
Compare the first bytes of two strings.
strpbrk(3)
Find the first occurrence in a string of one of the bytes
in the accepted bytes.
strrchr(3)
Find the last occurrence of a character in a string.
strsep(3)
Extract the initial field in a string that is delimited by
one of the delimiter bytes.
strspn(3)
Calculate the length of the initial segment of a string
that consists entirely of accepted bytes.
strstr(3)
Find the first occurrence of a substring in a string.
strtok(3)
Extract tokens from a string that are delimited by one of
the delimiter bytes.
strxfrm(3)
Transforms a string to the current locale and copies the
first bytes to a buffer.
strncpy(3)
Fill a fixed-size buffer with leading non-null bytes from a
source array, padding with null bytes as needed.
The string functions perform operations on null-terminated
strings. See the individual man pages for descriptions of each
function.
