const char* uint64_to_str | ( | uint64_t | value, | |
uint32_t | slot | |||
) |
Convert uint64_t to a string.
Convert the given value to a string with locale-specific thousand separators, if supported by the snprintf() implementation. The string is stored into an internal static buffer indicated by the slot argument. A pointer to the selected buffer is returned.
This function exists, because non-POSIX systems don't support thousand separator in format strings. Solving the problem in a simple way doesn't work, because it breaks gettext (specifically, the xgettext tool).

const char* double_to_str | ( | double | value | ) |
Convert double to a string with one decimal place.
This is like uint64_to_str() except that this converts a double and uses exactly one decimal place.
bool is_empty_filename | ( | const char * | filename | ) |
Check if filename is empty and print an error message.

bool is_tty_stdin | ( | void | ) |
Test if stdin is a terminal.
If stdin is a terminal, an error message is printed and exit status set to EXIT_ERROR.

bool is_tty_stdout | ( | void | ) |
Test if stdout is a terminal.
If stdout is a terminal, an error message is printed and exit status set to EXIT_ERROR.
