strdupa(3)

NAME

strdupa - string duplicate using-alloca

Standard C library (libc, -lc)

#define _GNU_SOURCE  /* See feature_test_macros(7) */
#include <string.h>

char *strdupa(const char *s);

strdupa() is similar to strdup(3), but uses alloca(3) to allocate the buffer.

It is equivalent to

strcpy(alloca(strlen(s) + 1), s)

On success, this macro returns a pointer to the duplicated string.

For an explanation of the terms used in this section, see attributes(7).
