BUGS

The standard buffered functions do not interact well with certain other library and system functions, especially vfork and abort. This may not be the case under Linux.

STANDARDS

The stdio library conforms to ANSI C3.159-1989 (ANSI C).

stpcpy

stpcpy—Copies a string returning a pointer to its end

SYNOPSIS

#include <string.h>
char *stpcpy(char *dest, const char *src);

DESCRIPTION

The stpcpy() function copies the string pointed to by src (including the terminating \0 character) to the array pointed to by dest. The strings may not overlap, and the destination string dest must be large enough to receive the copy.

RETURN VALUE

stpcpy() returns a pointer to the end of the string dest (that is, the address of the terminating null character) rather than the beginning.

EXAMPLE

For example, this program uses stpcpy to concatenate foo and bar to produce foobar, which it then prints:

                 #include <string.h>

                 int
                 main (void)
                 {

                   char *to = buffer;
				   to = stpcpy (to, "foo");
                   to = stpcpy (to, "bar");
                   printf ("%s\n", buffer);
                 }

CONFORMS TO

This function is not part of the ANSI or POSIX standards, and is not customary on UNIX systems, but is not a GNU invention either. Perhaps it comes from MS-DOS.

strcasecmp, strncasecmp

strcasecmp, strncasecmp—Compare two strings, ignoring case

SYNOPSIS

#include <string.h>
int strcasecmp(const char *s1, const char *s2);
int strncasecmp(const char *s1, const char *s2, size_t n);

DESCRIPTION

The strcasecmp() function compares the two strings s1 and s2, ignoring the case of the characters. It returns an integer less than, equal to, or greater than zero if s1 is found, respectively, to be less than, to match, or be greater than s2.

The strncasecmp() function is similar, except it only compares the first n characters of s1.

RETURN VALUE

The strcasecmp() and strncasecmp() functions return an integer less than, equal to, or greater than zero if s1 (or the first n bytes thereof) is found, respectively, to be less than, to match, or be greater than s2.

strcat, strncat

strcat, strncat—Concatenate two strings

SYNOPSIS

#include <string.h>
char *strcat(char *dest, const char *src);
char *strncat(char *dest, const char *src, size_t n);
