- * Utility string macros. All assume a variable holds the current
- * character and the string pointer points to the next character to
- * be processed. Typical setup is:
- *
- * s = buffer;
- * ch = *s++;
- * skip_whitespace(s, ch);
- * ...
- *
- * If you advance the pointer "by hand" to skip over something, do
- * it like this:
- *
- * s += some_amount;
- * ch = s[-1];
- *
- * Note that ch has the character at the end of the just skipped field.
- * It is often useful to terminate a string, make a copy, then restore
- * the input like this:
- *
- * skip_whitespace(s, ch);
- * fp = s-1; ## save the start
- * skip_nonwhitespace(s, ch); ## find the end
- * p[-1] = '\0'; ## temporary terminate
- * field = stralloc(fp); ## make a copy
- * p[-1] = ch; ## restore the input
- *
- * The scanning macros are:
- *
- * skip_whitespace (ptr, var)
- * -- skip whitespace, but stops at a newline
- * skip_non_whitespace (ptr, var)
- * -- skip non whitespace
- * skip_non_whitespace_cs (ptr, var)
- * -- skip non whitespace, stop at comment
- * skip_integer (ptr, var)
- * -- skip an integer field
- * skip_line (ptr, var)
- * -- skip just past the next newline
- * strncmp_const (str, const_str)
- * -- compare str to const_str, a string constant
- * strncmp_const_skip (str, const_var, ptr, var)
- * -- like strncmp_const, but skip the string if a match is
- * found; this macro only tests for equality, discarding
- * ordering information.
- *
- * where:
- *
- * ptr -- string pointer
- * var -- current character
- *
- * These macros copy a non-whitespace field to a new buffer, and should
- * only be used if dynamic allocation is impossible (fixed size buffers
- * are asking for trouble):
- *
- * copy_string (ptr, var, field, len, fldptr)
- * -- copy a non-whitespace field
- * copy_string_cs (ptr, var, field, len, fldptr)
- * -- copy a non-whitespace field, stop at comment
- *
- * where:
- *
- * ptr -- string pointer
- * var -- current character
- * field -- area to copy to
- * len -- length of area (needs room for null byte)
- * fldptr -- work pointer used in move
- * if NULL on exit, the field was too small for the input
