xt_strupper(3)

NAME
xt_strupper() - Covert all lower case characters to upper

LIBRARY
#include <xtend/string.h>
-lxtend

SYNOPSIS
size_t  xt_strupper(char *str)

ARGUMENTS
str         Pointer to null-terminated string to be copied

DESCRIPTION
xt_strupper(3) converts lower case characters in a string to upper case, overwriting the original. It is functionally equivalent to xt_strlupper(str, str, strlen(str)). It is implemented separately for efficiency, since using xt_strlupper(3) for this purpose requires knowing or computing the length of the string and passing three arguments instead of one.

RETURN VALUES
Size of the src string.

EXAMPLES
char    src[] = "Some text",
dest    [DEST_SIZE + 1];
if ( xt_strlupper(dest, src, DEST_SIZE + 1) != DEST_SIZE + 1 )
    fputs("Warning: String truncated.n", stderr);
