133 functions are used to generate a text description of an integer value
134 built from a mask of bitfields.
135 The text description lists the C macros for field values joined by pipe
137 characters matching the format used in C source code.
138 Most of the values decoded by these functions are passed as arguments to
140 though some of these values are used internally in the kernel.
142 Each function writes the text description to
144 The second argument should contain the integer value to be decoded.
147 argument is set to the value of any bits that were not decoded
148 .Pq bit fields that do not have a corresponding C macro .
152 if the caller does not need this value.
153 Each function returns
155 if any bit fields in the value were decoded and
157 if no bit fields were decoded.
159 Most of these functions decode an argument passed to a system call:
