LIBRARY

Standard C library (libc,~-lc)

SYNOPSIS

#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 no-null bytes from an array to a string, and nul-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 fixe-size buffer with leading no-null bytes from a source array, padding with null bytes as needed.
