.SH NAME
|
|
wofi \- Map API functions and documentation
|
|
|
|
.SH DESCRIPTION
|
|
The functions documented here are used for interacting with wofi's config and map. They are defined in map.h.
|
|
|
|
.SH MAP FUNCTIONS
|
|
The following functions are used to interact with a \fBstruct map*\fR
|
|
|
|
.TP
|
|
.B struct map* map_init(void)
|
|
Allocates and returns a new string map. String maps only support string values.
|
|
|
|
.TP
|
|
.B struct map* map_init_void(void)
|
|
Allocates and returns a new void map. A void map supports values of any type.
|
|
|
|
.TP
|
|
.B void map_free(struct map* map)
|
|
Frees the provided map and all it's keys. Values are only freed if it is a string map.
|
|
|
|
.TP
|
|
.B bool map_put(struct map* map, const char* key, char* value)
|
|
Returns true if the given map is a string map, otherwise returns false and prints a message to stderr.
|
|
|
|
.B struct map* map
|
|
\- The map to insert into.
|
|
|
|
.B const char* key
|
|
\- The key to store the value under. This key is given to \fBstrdup()\fR before being saved and will be freed when running \fBmap_free()\fR.
|
|
|
|
.B char* value
|
|
\- The value to store. This value is given to \fBstrdup()\fR before being saved and will be freed when running \fBmap_free()\fR. If the value is \fBNULL\fR it will not be given to \fBstrdup()\fR.
|
|
|
|
.TP
|
|
.B bool map_put_void(struct map* map, const char* key, void* value)
|
|
Returns true if the given map is a void map, otherwise returns false and prints a message to stderr.
|
|
|
|
.B struct map* map
|
|
\- The map to insert into.
|
|
|
|
.B const char* key
|
|
\- The key to store the value under. This key is given to \fBstrdup()\fR before being saved and will be freed when running \fBmap_free()\fR.
|
|
|
|
.B void* value
|
|
\- The value to store. This pointer is stored in the map, it is on the caller to free this and it will not be freed when running \fBmap_free()\fR.
|
|
|
|
.TP
|
|
.B void* map_get(struct map* map, const char* key)
|
|
Returns the value stored under \fBkey\fR or \fBNULL\fR if no key exists. \fBNULL\fR can also be returned if it was stored there with \fBmap_put()\fR or \fBmap_put_void()\fR.
|
|
|
|
.B struct map* map
|
|
\- The map to get the value from.
|
|
|
|
.B const char* key
|
|
\- The key to lookup.
|
|
|
|
.TP
|
|
.B bool map_contains(struct map* map, const char* key)
|
|
Returns true if the key exists, false otherwise. This is implemented as a \fBvalue != NULL\fR check so a \fBNULL\fR value is considered to not exist.
|
|
|
|
.B struct map* map
|
|
\- The map to check against.
|
|
|
|
.B const char* key
|
|
\- The key to check for.
|
|
|
|
.TP
|
|
.B size_t map_size(struct map* map)
|
|
Returns the number of entries in this map.
|
|
|
|
.B struct map* map
|
|
\- The map to get the size of.
