134 | * 'cupsResolveConflicts()' - Resolve conflicts in a marked PPD. | |
135 | * | |
136 | * This function attempts to resolve any conflicts in a marked PPD, returning | |
06d4e77b MS |
137 | * a list of option changes that are required to resolve them. On input, |
138 | * "num_options" and "options" contain any pending option changes that have | |
139 | * not yet been marked, while "option" and "choice" contain the most recent | |
e78998df MS |
140 | * selection which may or may not be in "num_options" or "options". |
141 | * | |
142 | * On successful return, "num_options" and "options" are updated to contain | |
143 | * "option" and "choice" along with any changes required to resolve conflicts | |
06d4e77b MS |
144 | * specified in the PPD file and 1 is returned. |
145 | * | |
146 | * If option conflicts cannot be resolved, "num_options" and "options" are not | |
147 | * changed and 0 is returned. | |
e78998df | 148 | * |
06d4e77b MS |
149 | * When resolving conflicts, @code cupsResolveConflicts@ does not consider |
150 | * changes to the current page size (@code media@, @code PageSize@, and | |
151 | * @code PageRegion@) or to the most recent option specified in "option". | |
152 | * Thus, if the only way to resolve a conflict is to change the page size | |
153 | * or the option the user most recently changed, @code cupsResolveConflicts@ | |
154 | * will return 0 to indicate it was unable to resolve the conflicts. | |
155 | * | |
156 | * The @code cupsResolveConflicts@ function uses one of two sources of option | |
157 | * constraint information. The preferred constraint information is defined by | |
e78998df | 158 | * @code cupsUIConstraints@ and @code cupsUIResolver@ attributes - in this |
06d4e77b | 159 | * case, the PPD file provides constraint resolution actions. |
e78998df | 160 | * |
06d4e77b | 161 | * The backup constraint information is defined by the |
e78998df | 162 | * @code UIConstraints@ and @code NonUIConstraints@ attributes. These |
06d4e77b MS |
163 | * constraints are resolved algorithmically by first selecting the default |
164 | * choice for the conflicting option, then iterating over all possible choices | |
165 | * until a non-conflicting option choice is found. | |
