NAMEexplain_pwrite_or_die - seek and write to a file descriptor and report errors SYNOPSIS#include <libexplain/pwrite.h> ssize_t explain_pwrite_or_die(int fildes, const void *data, size_t
data_size, off_t offset);
DESCRIPTIONThe explain_pwrite_or_die function is used to call the pwrite(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_pwrite(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_pwrite_on_error function is used to call the pwrite(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_pwrite(3) function, but still returns to the caller. RETURN VALUEThe explain_pwrite_or_die function only returns on success, see pwrite(2) for more information. On failure, prints an explanation and exits, it does not return. The explain_pwrite_on_error function always returns the value return by the wrapped pwrite(2) system call. EXAMPLEThe explain_pwrite_or_die function is intended to be used in a fashion similar to the following example: ssize_t result = explain_pwrite_or_die(fildes, data, data_size, offset); SEE ALSO
