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