Function Variants This function also has variants named _strncpy32 and _strncpy64 for use with 32-bit and 64-bit pointer sizes, respectively. See Section 1.8 for more information on using pointer-size-specific functions.

Arguments

str_1, str_2
Pointers to character strings.
maxchar
The maximum number of characters to copy from str_2 to str_1 up to but not including the null terminator of str_2.

Description

This function copies no more than maxchar characters from str_2 to str_1, up to but not including the null terminator of str_2. If str_2 contains less than maxchar characters, str_1 is padded with null characters. If str_2 contains greater than or equal to maxchar characters, as many characters as possible are copied to str_1. Be aware that the str_1 argument might not be terminated by a null character after a call to strncpy.

Return Value
x  The address of str_ 1.
