PetscStrncpy

Copies a string up to a certain length

Synopsis

#include "petscsys.h"   
PetscErrorCode  PetscStrncpy(char s[],const char t[],size_t n)
Not Collective

Input Parameters

t - pointer to string
n - the length to copy

Output Parameter

s - the copied string

Note

Null string returns a string starting with zero

If the string that is being copied is of length n or larger then the entire string is not copied and the final location of s is set to NULL. This is different then the behavior of strncpy() which leaves s non-terminated if there is not room for the entire string.

Developers Note: Should this be PetscStrlcpy() to reflect its behavior which is like strlcpy() not strncpy()
