man wnscan (Fonctions bibliothèques) - scan cstream for patterns
NAME
wn_scan_for_eos, wn_scan_for_char, wn_scan_for_char_type, wn_scan_for_not_char_type, wn_scan_for_literal - scan cstream for patterns
SYNOPSIS
#include <wn/wncstr.h> bool wn_scan_for_eos(stream) wn_cstream stream; bool wn_scan_for_char(stream,c) wn_cstream stream; char c; bool wn_scan_for_char_type(stream,char_type) wn_cstream stream; char char_type[256]; bool wn_scan_for_not_char_type(stream,char_type) wn_cstream stream; char char_type[256]; bool wn_scan_for_literal(stream,literal) wn_cstream stream; char literal[];
DESCRIPTION
These routines scan stream for the indicated pattern. They return TRUE and set the current mark to the beginning of the pattern if successful. Otherwise, they return FALSE and leave current mark unaltered.
wn_scan_for_char_type scans for a character c which satisfies char_type[c] == TRUE. wn_scan_for_char_type returns FALSfP if such a char cannot be found.
wn_scan_for_not_char_type scans for a character c which satisfies char_type[c] == FALSE. End of stream is considered to be a match, so wn_scan_for_not_char_type always succeeds.
BUGS
More scan routines are needed.
Need routines to scan between 2 marks rather than between a mark and end of stream.
Need routines to scan backward.
What about scan for regular expressions?
