.Dd February 24, 1997 .Os NetBSD 1.3 .Dt STRINGLIST 3 .Sh NAME .Nm stringlist , .Nm sl_init , .Nm sl_add , .Nm sl_free , .Nm sl_find .Nd stringlist manipulation functions .Sh LIBRARY .Lb libc .Sh SYNOPSIS .Fd #include <stringlist.h> .Ft StringList * .Fn sl_init .Ft void .Fn sl_add "StringList *sl" "char *item" .Ft void .Fn sl_free "StringList *sl" "int freeall" .Ft char * .Fn sl_find "StringList *sl" "char *item" .Sh DESCRIPTION The .Nm functions manipulate stringlists, which are lists of strings that extend automatically if necessary.
p The .Ar StringList structure has the following definition: d -literal -offset indent typedef struct _stringlist { char **sl_str; size_t sl_max; size_t sl_cur; } StringList; .Ed
p l -tag -width "sl_str" -offset indent t Ar sl_str a pointer to the base of the array containing the list. t Ar sl_max the size of .Ar sl_str . t Ar sl_cur the offset in .Ar sl_str of the current element. .El
p The following stringlist manipulation functions are available: l -tag -width "sl_init()" t Fn sl_init Create a stringlist. Returns a pointer to a .Ar StringList . t Fn sl_free Releases memory occupied by .Ar sl and the .Ar sl->sl_str array. If .Ar freeall is non-zero, then each of the items within .Ar sl->sl_str is released as well. t Fn sl_add Add .Ar item to .Ar sl->sl_str at .Ar sl->sl_cur , extending the size of .Ar sl->sl_str t Fn sl_find Find .Ar item in .Ar sl , returning NULL if it's not found. .El .Sh SEE ALSO .Xr free 3 , .Xr malloc 3
