The pblock_find macro finds a specified name-value pair entry in a pblock, and returns the pb_param structure. If you only want to find the value associated with the name, use the pblock_findval function.
Parameter names are case sensitive. By convention, lowercase names are used for parameters that correspond to HTTP header fields.
pb_param *pblock_find(char *name, pblock *pb);
A pointer to the pb_param structure if found, or NULL if the name is not found.
char *name is the name of a name-value pair.
pblock *pb is the pblock to be searched.
