BZERO(3P) POSIX Programmer's Manual BZERO(3P)PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the corresponding
Linux manual page for details of Linux behavior), or the interface may
not be implemented on Linux.
NAMEbzero - memory operations (LEGACY)
void bzero(void *s, size_t n);
The bzero() function shall place n zero-valued bytes in the area
pointed to by s.
The bzero() function shall not return a value.
No errors are defined.
The following sections are informative.
The memset() function is preferred over this function.
For maximum portability, it is recommended to replace the function call
to bzero() as follows:
#define bzero(b,len) (memset((b), '\0', (len)), (void) 0)
This function may be withdrawn in a future version.
