When documenting kernel functions you 172# should document the "Context:" of the function, e.g. whether the functions 173# can be called form interrupts. Unlike other sections you can end it with an 174# empty line. 175# A non-void function should have a "Return:" section describing the return 176# value(s). 177# Example-sections should contain the string EXAMPLE so that they are marked 178# appropriately in DocBook. 179# 180# Example: 181# /** 182# * user_function - function that can only be called in user context 183# * @a: some argument 184# * Context: !in_interrupt() 185# * 186# * Some description 187# * Example: 188# * user_function(22); 189# */ 190# ... 191# 192# 193# All descriptive text is further processed, scanning for the following special 194# patterns, which are highlighted appropriately. 195# 196# 'funcname()' - function 197# '$ENVVAR' - environmental variable 198# '&struct_name' - name of a structure (up to two words including 'struct') 199# '@parameter' - name of a parameter 200# '%CONST' - name of a constant. 201 202## init lots of data 203 204my $errors = 0; 205my $warnings = 0; 206my $anon_struct_union = 0; 207 208# match expressions used to find embedded type information 209my $type_constant = '\%([-_\w]+)'; 210my $type_func = '(\w+)\(\)'; 211my $type_param = '\@(\w+)'; 212my $type_struct = '\&((struct\s*)*[_\w]+)'; 213my $type_struct_xml = '\\&((struct\s*)*[_\w]+)'; 214my $type_env = '(\$\w+)'; 215my $type_enum_full = '\&(enum)\s*([_\w]+)'; 216my $type_struct_full = '\&(struct)\s*([_\w]+)'; 217my $type_typedef_full = '\&(typedef)\s*([_\w]+)'; 218my $type_union_full = '\&(union)\s*([_\w]+)'; 219my $type_member = '\&([_\w]+)((\.|->)[_\w]+)'; 220my $type_member_func = $type_member .
